Hello and welcome to JustAnswer!

There are several things that will cause a no start condition and it will require some testing to determine what is going on. If it cranks but does not start you could be missing fuel pressure, spark, it's possible that there could be a fuel quality issue or exhaust restriction.

The first step in diagnosing the problem will be to use a scan tool or code reader to check for fault codes. Have you checked for codes?
