First off I feel I should give a little backround history on this project. Please bear with me:

I recently bought a 96 camao Z28 that had been sitting for a year with a bad engine. When I got the car home I was able to get it started although it ran really rough. The previous owner had run it out of oil and it was knocking really bad. I replaced the engine with one I've had out of a 95 caprice cop car. The engine has been sitting on the engine stand for about 6 years in my shop. I swapped everything over from the 96 engine to make it work (timing cover, crank position sensor, crank hub, various other sensors etc.). I also deleted the EGR, EVAP, air pump and catalyc convertors then sent the pcm to pcmforless to be re programmed. VATS deleted as well. Here in Oklahoma we don't have to worry about emissiions checks. I also drained the fuel tank, filled with new gas and some injector cleaner, flushed the fuel line and replaced the fuel filter.

Now for the problem. When I try to start the car it turns over and acts like it wants to start every couple of revolutions but doesn't start. I can squirt gas in the intake and it will fire up for a couple of seconds then die. I checked the fuel pressure and it is 78 psi when I turn the key to run but don't crank. When i crank it the fuel pressure stays around 70 psi. I checked the pressure on another LT1 car of mine just to make sure the guage wasn't faulty and it checked out fine (42 with key on, 38 when cranking).

I'm thinking there's possibly an obstruction in the fuel rail or maybe the injectors are stuck shut from sitting for so long. I just want to make sure I haven't missed something before I pull the fuel rails and injectors. Any input is greatly appreciated.
