motor Turns Over But Doesn't Start

Your machine turns over, but will not start. Before you send your mind in a million directions reasoning about what it might be, you should remember the K.I.S.S. Method (Keep It simple Stupid.) There are fullness of reasons that a contemporary motor will turn over but will not crank up. Don't worry about all of those hundreds of parts that could cause this problem. Focus instead on the basics.

Spray Paint On Cars

Does your machine have fuel and does it have spark? Those are the only two things you machine needs to run. First check to see it if your car has any spark. Remove a spark plug and place it back into the plug wire or coil that went on top of it. Hold the bottom of the spark plug on a good ground like the valve cover or exhaust manifold, and have someone crank the motor. If you see a spark then go to testing the fuel, if you do not see a spark then it's time to chase that issue.

You have spark then find a can of starting fluid or flammable brake cleaner to spray into the air intake, and please don't use paint. Since you have a spark and you are now introducing fuel, your machine should start. That means your car is not delivering fuel to your motor. Start to see if your car is delivering fuel via the fuel pump, and work your way through the no fuel issue tree here.

If you didn't have any spark you could be seeing at a amount of issues. Start simple and see if you are getting spark through your coil or one coil pack. If you have no spark arrival from a coil then you will need to get a wiring diagram for your vehicle and check you power and grounds.

Some of this may seem very complicated, but it's only as hard as you make it. Find some easy to understand data on electrical diagnosis and learn how easy it is to indeed understand. One you understand you electrical system on your car you can fix roughly anything.
