Answer
Hi
I would check fuel pressure, first. I would also have the PCM (control Module) scanned for any possible Throttle body codes, or any other codes CKP (Crankshaft sensor) or CMP (Camshaft sensor) any of these could cause a crank but no start.
If these 2 items check out, I would then check for spark at 2 or more of the coils/plugs to make sure you getting fire to the spark plugs.
I Hope this helps.
