Why is my snowmobile not getting spark?

Disconnect the main electrical connector coming out of the engine, and then check for spark again. This unhooks the kill switch, ignition switch and wiring for those switches. If the spark improves, the problem is within wiring from one of those switches or a switch itself is to blame.

What makes a snowmobile hard to start?

Your starting issue could be damaged gaskets or maybe worn-out piston rings, scored cylinder or piston, bad crank seal, reed valve, or a damaged head gasket. Using a compression tester or contacting a place that can service your snowmobile will be the best way to go if the problem looks too serious

Where do you spray starting fluid on a snowmobile?

Spray it into the carburetor intake and turn the engine. It should start at least momentarily. If it shuts off after burning off the starting fluid, it means you’re not getting enough gas coming in. if this happens a few times, your carburetor probably needs to be cleaned

How do I know if my snowmobile fuel pump is bad?

One of the biggest signs your snowmobile has a bad fuel pump is when you routinely lose power whether you’re climbing a hill or going at high speed. In many cases, lost power is actually a sign of another problem such as an engine issue or a pinched fuel line.

How do you tell if a snowmobile is flooded?

As discussed you can use carby (carburetor) spray as an alternative to starting fluid. We do recommend specific engine starting spray when available as the pressure is lower and the nozzle on the can creates more of a mist.

What to do when your snowmobile won't start – Dennis Kirk

What to do when your snowmobile won’t start – The Aftermarket Experience 98 Arctic Cat Jag 440 sat for last 2 yrs and won’t start. New plugs, gas, and fuel pump, carbs clean, got spark and compression. Almost popped off with gas in the plugs, but back to nothing…HELP! Hi Brian, If you call our tech support at 320-358-3409, they should be able to help you troubleshoot your problem. hey i have a 92 cougar 440 it wont start any ideas or numbers to call I have a 98 skidoo mxz 670ho it overheated but I shut it off I think b4 it got to hot. Now I cant get it to fire back up after it cooled down and I replaced the plugs and I filled coolant and fixed hole in re as r in line. Any help? What else it could have fired? Remove the plugs and dry out plugs and pull over engine to clear out any gas in it. Add a few drops of 50:1 Injector oil or and put plugs in and pull choke and start as normally. This gives the engine a little oil on top pistons and side walls to make a good suction and seal to pull gas when u have a dry not used engine. I have a 2012 summit 800 rev xp I just started it for the first time this year it started ran for its warm up time I drove it out of the garage into the yard and started to stall when I let off the throttle now won’t start at all. Any help would be appreciated can email me at [email protected] or text me at 16395410019 Why does it mean when my snowmobile start then dies Hi, this could be a few problems with your fuel. Usually, when that happens, your fuel system is not delivering enough fuel to keep it running. You will want to check your in line fuel filter and the pick up fuel filter. They could be plugged with dirt and debris. Most likely, you will want to clean your carbs. If you would like any direct help with this issue, you can contact our techs at 320-358-3409 Hey Ryan I have a 95 xcr 440 sp and I’m not sure where the pick up fuel filter is, could you let me know? Thanks Hi Reed, the pickup filter should be attached to the line in the tank. If there isn’t one there, I would put one on. Hi i have a 1997 artic cat puma 340 2up and i was just running it a month ago and was doing everything perfect. i then went on a vacation so i was gone. today i went out to start it and nothing pulled it about 15 times so i pulled up the hood and no fuel was going through i checked the carb to see if there was gunk in there and nothing i still wiped it out and cleaned it with carb cleaner just to make sure. no fuel gets to the carb idk whats wrong Will low fuel b a problem from running I have a 94 Polaris INDY XLT that has sat for a few years. We can get it started with starting fluid but it won’t stay running. Plugs are clean and new, pumped out the old gas and replaced it with new gas. We have got it to move about twenty feet but then it dies. I haven’t done much work on snowmobiles before so was just wondering if you had any ideas on what I could try to get it running. Thank you! Hey Nolan, It sounds like you are not getting enough fuel. Check all of your fuel lines and filters, including the pick up in the tank, and make sure that they are still letting the fuel flow through. Next, since it’s sat a few years, you’ll probably need to clean the…

11-POINTS TO CHECK WHEN TROUBLESHOOTING A NON-STARTING SNOWMOBILE – The Rop Shop How-To Installation Product & Troubleshooting Problems Power Sport, ATV, UTV, Snowmobiles, Dirt Bikes, and Off-Roading January 13, 2021 If your snowmobile won’t start, don’t call a mechanic just yet. You spent your summer on your boat or jet ski and really hadn’t thought about your snowmobile in months. Now that there is a chill in the air, and snow begins to fall, you are ready to trade in your bathing suit for a snowsuit. So you jump on your sled, and try to crank it over and… nothing. Use these 11-points to narrow down the cause, so you can get out on the powder. Man pushing his snowmobile that wont start 1. NO FUEL IN THE TANK Is it really all that surprising that you forgot you had removed all the gas at the end of last season? Sounds silly, but it happens. You’ve slept since then. You worked and played hard elsewhere for the last 8 months or more. So, this is the easiest and first item to check off your list.2. SWITCHED ‘ON’ OR ‘OFF’? D’OH! Yeah, rookie mistake right? This is the next easiest troubleshoot to look at. Check and see if your switch is set to ‘ON’ or ‘OFF’. Then don’t tell ANYONE what happened if it works. 3. REPLACE OLD GAS WITH NEW GAS Just like with your lawnmower, pressure washer, or snowblower, your snowmobile will tend to sit for months. With any outdoor equipment that runs off gasoline, there is a shelf-life. Even if you use a stabilizer, your gas could still be old. It is best to run your equipment out of gas, but if you are one who uses a stabilizer and shut-off valve, this could be your culprit. Empty the fuel in the tank and replace it with fresh new gas. 4. BAD BATTERY OR FAULTY WIRING Like your gasoline, your battery remains unused for many months at a time. A battery’s life cycle can be drastically cut short due to inactivity. Batteries will typically last 2-3 years when properly used. If the battery has a charge going through it during the off-season, it will be able to survive its life expectancy. An inactive battery will discharge and continue to break down internally. A smart/trickle charger can protect the battery. Checking over the condition of your wiring and connections is also a good idea. You can even take a look at your voltage regulator. We tend to forget that these sleds are exposed to the elements. Even though they may have a protective shroud over key components, it’s always best to give them a look. 5. SPARK PLUGS BRING LIFE It is really amazing how such small parts of an engine can be the life and death of a snowmobile. Spark plugs ignite the fuel, sending a blast of raw power through your snowmobile. If defective, you won’t be able to operate the sled. The good news is, The ROP Shop carries many sizes, and at a very affordable price. 6. OLD OIL AND OIL FILTERS Just as vital as it is to change the oil in your automobile, changing the oil in your snowmobile is equally necessary. Failure to change the oil over long periods of time can trigger other complications including failure to start, and while you are at it, replacing the oil filter is a good idea too. We just might have the one you need. 7. FUEL LINES CHECKUP Your fuel lines could be blocked. This would then prevent gas from entering the engine. To examine the lines, remove the shroud covering the motor. You can also look at your Fuel Primer/Plunger for issues, or replace it with one of our Fuel Primer/Plungers from The ROP Shop. The other end of the spectrum from a clogged fuel line is one that has dried out, which we will address in the next point. 8. CARBURETOR CLEANER AND STARTING FLUID Fuel lines…

10 Reasons Why Your Snowmobile Won't Start or Accelerate …

10 Reasons Why Your Snowmobile Won’t Start or Accelerate [Video] | If your snowmobile won’t start or accelerate, it’s usually because of fouled spark plugs, fuel or carb issues, or perhaps a flooded engine. If your snowmobile has a battery, its failure, or a bad starter could also be why your sled won’t start. If your snowmobile won’t start or accelerate properly, this post is for you. In addition to the typical issues mentioned above, we’ve compiled many other potential problems and their fixes under one roof. Let’s see how to troubleshoot a snowmobile step-by-step! Why is My Snowmobile Not Starting? There could be several reasons why your snowmobile won’t start, but some issues are more common than others. The following problems are the most common, so it’s recommended that you check for them one-by-one: Dead batteryCarb/fuel/fuel line problemsBad starter/starter relay/coils (no spark)Dirty or defective spark plugs / wrong gap settingsIncorrect ignition timingStop switch malfunctionDamaged computerFlooded engineLow compression in the cylindersBroken piston rings, or some other major engine damage  (Disclaimer: Before you start to service your sled, always read the owner’s manual carefully. If you don’t have mechanical skills, best practice is to take the sled to your dealer or a reputable service shop.) Dead Battery One of the most common reasons why a snowmobile won’t start is a dead battery. However, not every sled has a battery, but if it features an electric start then it has a battery as well. It’s important to know that snowmobile batteries self-discharge over time. That’s why you should keep it on a battery tender during the summer or when you aren’t using your sled for a long period of time. If you notice that your snowmobile’s battery is weak, just give it a good charge and try starting the engine again. Best practice is to let it charge overnight. Starter and Starter Relay If your snowmobile features an electric start, this means it has a starter and a starter relay. These parts can also sometimes go wrong. If you hear one or more clicks but your snowmobile still won’t start, you should check these parts. As a rule of thumb, you can determine the cause of the problem by the number of clicks. If you hear multiple clicks, it’s a sign of a week battery. If you’ve charged the battery but your sled still won’t start, check the battery with a voltmeter. It might be so dead that it needs to be replaced. If the starter relay makes only one click, this usually means that there is an issue with the relay. If it’s broken, you will need to replace it. Before replacing it, it would be wise to remove and test it. Here’s a good step-by-step video on how to test a snowmobile starter relay: It’s also good to know that snowmobile starter relays are sometimes called starter solenoids as well. Spark Plugs Sparks are also essential for a snowmobile engine to start. The sparks are generated by the spark plugs, which are fortunately easy to test and replace. Bad or fouled spark plugs is one of the leading reasons why snowmobile engines won’t start, especially on carbureted 2-stroke sleds. To replace the spark plugs, you just need a socket wrench with an extension. Remove the plugs and examine them. If they have a light brown color while being completely dry, it’s a clue that the fueling…

Why Won't My Snowmobile Start? – Outdoor Troop

Why Won’t My Snowmobile Start? | Outdoor Troop Whether your snowmobile uses an electronic start or even a classic pull cord, when you go to turn on the ignition and nothing happens, it’s scary. You give your sled’s ignition another try and nothing. What is going on and why won’t your snowmobile start? Your snowmobile might not start for these reasons: Altitude changesDamaged head gasketBroken/worn cylinder parts Low cylinder compressionDead spark plugsFuel line blockages or the line dried outLeftover old gas in the tank  As you might have assumed, there is a lot that could be going on behind the scenes that’s preventing your snowmobile from starting. Ahead, we’ll talk about each of the above issues in more detail so you can diagnose your sled and get it running again.  8 Reasons Your Snowmobile Won’t Start You Changed Your Altitude If you own a mountain snowmobile in particular, you’re used to scaling ascending altitudes on your snowmobiling treks. Yet the next time you start at too high an altitude, you might notice that your sled doesn’t want to turn on.  It’s always best if you’re at ground level or close to it when starting your snowmobile. Otherwise, changing from one altitude to another between now and the last time you used your sled can fail to get it started. By adjusting your engine settings to the higher altitude, this issue is easily fixable.  Damaged Head Gasket The gaskets in your cylinder deserve a little of your attention, especially the head gasket. This gasket separates the cylinder head and the engine block if your snowmobile has an internal combustion engine, which is overwhelmingly common.  The head gasket also prevents engine oil and coolant from leaking from your engine to the cylinders. More importantly, this gasket maintains cylinder compression by creating a seal. We’ll touch on why cylinder compression is such a big deal later in this article, so keep reading.  If your snowmobile’s head gasket is done for, you’ll be able to tell in a variety of disturbing ways. Your snowmobile will overheat more often as the combustible gases and coolant mix regularly. Any lubricant you add to your sled’s internal components will erode fast because the head gasket seals are broken. The engine can get flooded with oil, which is about the worst-case scenario. You’d then have to buy a new engine, which would put a major hurting on your wallet. The catalytic converter can also end up wrecked through a bad head gasket. Gaskets, like any part of your snowmobile, can wear down with time or misuse. The longer your sled’s head gasket goes without a repair and ideally a replacement, the worse the outcome for your snowmobile.  Broken or Worn Cylinder Parts If you thought that was the end of your cylinder worries, sorry to say, but we’re just getting started. A whole handful of cylinder parts can degrade or fail, all preventing your snowmobile from starting. These are the reed valve, crank seal, and piston rings. Let’s cover each component in more detail now. A reed valve is a check valve that knows when fluid is entering, where it’s coming from, and how much fluid should pass through the cylinders. Depending on whether you need more fluid or less, the reed valve can open or close as appropriate. The pressure changes as well. Admittedly, reed valves are pretty hardy, as they’re often made of carbon fiber or fiberglass. That doesn’t mean your snowmobile’s reed valve is forever. When it stops working, fluids can flood the cylinder and even the engine, causing some of the issues we discussed in the last section. The crank seals of your cylinders can also malfunction. Crankshaft seals at the front of the sled’s engine maintain the flow of oil the crankshaft relies on, keeping the oil in the crankcase. If oil leaks, it can accumulate around the oil and again flood it out.  As most crank seals are only rubber, their lifespan isn’t super long. They can wear down to nothing or go bad on you when you least expect it. Finally, let’s discuss the cylinder piston…

Need help, my sled won't start… – Snowmobile Forum

Need help, my sled won’t start… Joined Dec 28, 2008 ·17 Posts Discussion Starter · #1 · Jan 11, 2009 My ’80 Mirage 2 with the 377 refuses to start. I have spark and fuel, but it doesn’t even sound like it wants to start. It started on the first pull yesterday, but stalled out after about 10 seconds. That happened 3 times, until it wouldn’t start anymore. It sounded like a fuel issue, so with that in mind I found the awesome help page on here, and with that I took apart the carb for cleaning. The pilot jet was clogged solid, but after some tedious work it’s now nice and clean, along with the rest of the carb.

How to Start a Snowmobile after Sitting (7 Steps)

How to Start a Snowmobile after Sitting (7 Steps) A snowmobile that sits over the summer, or even longer, will probably need a little extra attention before starting it up again. With a handful of easy steps and precautions, you can make sure not to damage the engine and have the machine running strong.  I’m Chaz, a snowmobile aficionado with nearly 30 years of experience riding and wrenching on these machines. I’ve left a snowmobile sitting for quite a while and have learned how to approach starting it up through my own experience and talking to other riders.   In this article, I’ll show you how to start a snowmobile after it’s been sitting. Following all of these steps isn’t always necessary, but a little extra prevention can help eliminate more significant issues later on. Dust off your sled, and let’s get it started.  Things to Consider  Engines run better when they are used consistently. Oil and fuel move throughout all of the engine’s components to properly lubricate everything and work out gunk and sludge.  When an engine sits for an extended period, all sorts of issues can arise. Fuel lines and other hoses can begin to corrode, rust can build up, and creatures might even nest inside for the long winter (this has happened to me more than once).  It’s essential to perform a basic checkup on your snowmobile before starting the engine after it’s been sitting. You might not think that a few months in the garage can cause many problems, but ideally, you should start the engine once a week, even during the warmer months.  The following steps are suggested tips that I recommend completing before starting your sled after it’s been sitting. These don’t necessarily need to be completed in a particular order, but I would go through each one before turning over the ignition.  1. Drain fuel/replace fuel lines if needed If your snowmobile has old fuel sitting in the tank, it can pose issues when trying to start it. Fuel can leak out, become corrosive, and lose its lubricating properties.  I like to drain most of the fuel out of the tank before putting the sled away for the season. If you didn’t do this, just drain out all of the fuel and put new fuel and oil into the tank before you try to start things up.  With the fuel tank empty, check on the fuel lines and make sure they have not been corroded. If you see cracks or any other signs of wear, replace these lines before starting.  2. Inspect carbs: remove and clean If a snowmobile has been sitting for a while, the carbs will need a little attention. This can be bad because they can begin to rust or seize up. Before starting your sled, remove the carbs for a good inspection to make sure they look normal. With the carbs removed, I would give them a good cleaning even if they look ok.  Some people simply look at the carbs when still attached to the engine. This is ok, and you don’t necessarily have to clean them. But I would recommend it as a precaution and for general maintenance. …
