hard starting

[sinestr]

I have a 96CE/LT4 and after the car sits for several hours it will not start without cranking the engine several times. I had it to my mechanic, he said it needed a fuel pump and a new coil of which I had him replace both. The next morning same thing, I had to crank the engine several times to start. Could it be injectors? I assume I am losing pressure somewhere.

Had the same problem on my '95... fixed now!

Turned out to be the fuel pressure regulator in the fuel manifold. Corvette Mike in Anaheim replaced it and it fires up instantly now. Guess it acts like a check valve and if bad slowly lets the pressure bleed off and you have to crank it a few times to build it back up. If I recall, the repair ran me about $225-250, but thats just my bad memory.
