If you’ve ever gone out to start your ATV, only to find that your ATV crank but won’t start, you know how frustrating it can be. There are several potential reasons why this might happen, and fortunately, most of them are relatively easy to fix.
In this blog post, we’ll explore some of the most common reasons why your ATV might not be starting, so that you can get back out on the trails as soon as possible.
Reasons why your ATV Crank But Won’t Start
There are several reasons why an ATV may crank but not start. Here are some possible causes:
A common reason why an ATV won’t start is due to fuel problems. This can include issues such as an empty fuel tank, clogged fuel filter, or a faulty fuel pump.
Ignition system problems:
If there is an issue with the ignition system, it can prevent the ATV from starting. This can include problems such as a dead battery, faulty spark plug, or a faulty ignition switch.
If there is a problem with the electrical system, it can prevent the ATV from starting. This can include issues such as a blown fuse or a faulty starter motor.
If there is an issue with the engine itself, it can prevent the ATV from starting. This can include problems such as a seized engine, a faulty carburetor, or a broken timing chain.
Air intake issues:
If there is an issue with the air intake system, it can prevent the ATV from starting. This can include problems such as a dirty air filter or a blocked air intake.
It’s important to identify the root cause of the problem to properly diagnose and fix the issue. If you are unsure, it’s best to take your ATV to a qualified mechanic for an inspection.
Check the Battery
Before you do anything else, it’s important to check the battery. A dead or dying battery is often the reason an ATV won’t start.
To check the battery, first make sure that the cables are all connected properly. Then use a voltmeter to test the voltage of the battery. If it reads 12 volts or less, then the battery needs to be charged or replaced.
If the battery is fine, then move on to checking the other potential causes of why your ATV won’t start.
Check the Ignition Switch
If your ATV won’t start, the first thing you should check is the ignition switch. The ignition switch is responsible for supplying power to the engine starter, so if it’s not working properly, the engine won’t start.
To test the ignition switch, first make sure that the ATV’s battery is charged. Then, turn on the ignition switch and try to start the engine. If the engine doesn’t start, turn off the ignition switch and check the fuse box. If the fuse is blown, replace it with a new one. If the fuse isn’t blown, then the problem is likely with the ignition switch itself.
If you need to replace the ignition switch, it’s a relatively easy process. Just unscrew the old switch and screw in a new one in its place. Make sure that you screw it in tightly so that it makes good contact with the wires. Once you’ve done that, try starting the engine again and see if that solves the problem.
Check the Fuel System
If your ATV won’t start, the first thing you should check is the fuel system. If the fuel system is clogged or not working properly, the ATV won’t be able to get the gas it needs to run.
To check the fuel system, start by making sure that there is gas in the tank. If the tank is empty, fill it up and try again. If the tank is full, check the fuel line to make sure it’s not clogged. You can do this by disconnecting the fuel line at the carburetor and seeing if gas flows out when you turn on the ATV.
If there’s no gas flowing through the fuel line, there may be a problem with the fuel pump or filter. You’ll need to take your ATV to a mechanic to have these parts checked and replaced if necessary.
Check for a Loose Spark Plug
If your ATV won’t start, one possible reason is a loose spark plug. To check for a loose spark plug, follow these steps:
1. Remove the spark plug from the ATV’s engine.
2. Inspect the spark plug to see if it is damaged or dirty. If it is, replace it with a new one.
3. Re-install the spark plug into the engine and tighten it securely.
4. Attempt to start the ATV again and see if the problem has been resolved.
Check the Air Filter
If your ATV won’t start, one of the first things you should check is the air filter. A dirty air filter can restrict air flow to the engine, making it difficult to start.
To check the air filter, remove it from the ATV and hold it up to a light. If you can’t see through it, it’s time to replace it.
If your ATV won’t start, it could be due to a number of reasons. The most common reason is that the fuel isn’t reaching the engine. This can be due to a problem with the carburetor, fuel line, or filter.
Another possibility is that the spark plug isn’t firing correctly. This can be caused by a dirty spark plug or an issue with the ignition system. Whatever the reason, it’s important to diagnose and fix the problem so you can get back out on the trails as soon as possible.
