Hello,

Just to clarify the question, the engine will crank but not start? Is this what you are experiencing?

Generally speaking, an engine will need spark, fuel and compression to start. So, to figure out what is going on you will have to check each of those.
First of all, do you know if the fuel pump is turned on when the key is in on position? Typically, you should be able to hear the fuel pump run for a few seconds with a humming noise, when the key is at on position.
Also need to verify if there is spark to the plugs.

Here is a helpful guide:

Let me know of any questions.
Thank you.
