Hello,

If the engine is cranking over strong but not starting, it could be due to not having fuel or spark.
When you turn the key to the on position, can you hear your fuel pump kick on for a few seconds?
An inoperative fuel pump can be due to bad relay, faulty wiring or bad pump.

One way to check if it is a fuel delivery issue, is to spray starter fluid into the intake and try to start. If the engine starts for a few seconds, then you will know the issue is fuel.

If you are getting fuel, then you will need to check for spark to the plugs.

Take a look at this helpful guide:

Let me know what you find or if you have any questions.
Thank you.

I have got a new vent valve solenoid canister and a new battery that I put and it still does the same thing.
