Is the engine hitting or does it just turn over?
Because even if you have fuel pressur you may not be getting it in to the engine.

Re: Car wont start?????? (tntcorvette)
I just went through the same circumstance this week. It ended up being a fuel injector. Seems that if you have an open or shorted injector the driver shuts down and none of the injectors operate. We tested each with an ohm meter and when we disconnected the bad injector the car started right up and I drove it home. With the car started when I plug in the bad injector the engine stops. My new set of injectors arrived today from Jegs and I'm getting ready to twist wrenches this evening.
I'm installing Ford, SVO 24# injectors which comes highly recommended here on the forum, except for a few who said Ford SVO's are no good, however there were more ya's than na's and Jegs had them for 219 for a set of 8.
Good luck yell if you need info from the shop manual.

Sounds like your injectors are not being pulsed. You can put an analog voltmeter across an injector plug, or a 12v lamp and it should pulse when you crank the engine. The VATS tells the ECM that the right pellet is in the ignition switch and the ECM then pulses the injectors. I don't know how you bypassed the VATS, but it is worth looking into.

I may have missed some other posts before..did this run recently then all of a sudden wont?
Or,If this is the first fire up for the engine all put back together,you may need to slightly loosen the dist. and have someone proceed to start the car then you advance the dist. by hand...if this works,then tighten down when its running good.
I had the dist. dropped in,lined up,and all it would do was crank over and over..after some trying and advice,I turned it ALOT by hand and it began to fire and run.If this works and the timing is a bit far our,see if its been installed a tooth off or so.Been there and done that!!
Good luck.
