Please Read, problems after installation...3 seconds only...
I installed new shorty headers, new O2 sensors, new MSD Pro-Billet Optic Distributor, new MSD Blaster Coil, new MSD wires and new OEM AC plugs.
The Vette started right away and lasted 2 seconds, tried again, lasted 2-3 seconds, again, 3 seconds. I tried a fourth time and this one lasted a bit longer. The idle was a "perfect" idle, no shaking, no misfiring
I checked all connections, all are ok, all breathers and vacuums are plugged so, I decided to stop, disconnected the battery and wrapped it for the night.
Any toughts or ideas, what the heck may be wrong?

Put a gage on and check the fuel pressure at start up. If it drops like a rock check the oil pressure switch/relay as it has to be on to continue running the Fuel pump after start up.

I was thinking about this one. The car always starts and dies just about three seconds. I tried giving it fuel and died. I guess, I'll turn the screw to advance timing. I'll try that and if I'm unsuccessful...I'll come back here.

I thought this was an L98 so a timing change would be an easy test.
Is the timing on the LT1 checked the same way as the L98s so he can check where the base timing is at?
I do agree that the fuel system could do this. What is the fuel pump relay and oil pressure switch start/run sequence for the fuel system on a 95?
All I have is the manual for an 86.

I checked the fuel pressure...good
I played with timing turning the screw both ways...good, put it back to original position
I replaced the MSD coil and installed the AC Delco...good
Still, the same. It starts strong, a perfect idle then dies. I triple checked all connections, under the O2 sensors, and all relays are up.
I'm going crazy, I'm mad and fustrated

I don't get it I told you to check your fuel pressure when it is running and you come back with a fuel pressure is fine. What is fine what is it before start after start and after key shut off. THAT is a fuel pressure check. If you ask for help at least try and follow the easy stuff.I still put my money on the Oil Pressure switch or relay/Fuel starvation(remote chance of plugged filter) till you say the fuel pressure is around 40psi when it dies.

OK so now we have 2 of the 3 things you need Fuel and air. Gotta start looking at spark then. Got a timing light? Check for spark. Got any codes? Try pulling them usually if it is electrical there will be one.
