I'm having what's probably an easy fix somewhere. My 96 camaro z28 I recently changed out the optispark 3rd time after going through the ones bad out of the box. Reman Ac delco. I've tested it and lts good. But after installing it now the car will crank and start for a second when you try to give it gas it boggs down. Now this engine is new Remanufactured and just about everything on it is new. I'm not sure what the issue is because the fuel pump comes on. It does have fuel pressure, it has spark and oil and I've done voltage checking the grounds are all good. Need help figuring it out it was running just fine before the optispark change. I don't think I mixed up the plug wires. What does it sound like? Any help will do thanks.

 

Timing chain indexed incorrectly? Any chance it’s a Jasper reman engine?

Is it possible the cam dowel pin slipped out of the index hole in the Opti? It's happened before. Did you lock-tight the rotor screws?

What is the fuel pressure?
