This is for a 1996 Chevy Caprice (cop) LT1. I replaced opti for MSD distributor, cap, and coil along with ICM, wires and plugs, fuel pump, MAF, Fuel filter. Car now runs like a dream. But, since I made those changes, my car is hard starting after sitting for like 30 minutes. And that was never an issue before.
I have to sit there and just keep the key turned for about 10-12 seconds before it will fire up. While im cranking, it is not even trying to fire. There is no spark from the Coil. Then it will just fire up and run great. If I drive a few minutes and then shut it off and try to start again, it fires right up within a sec or two.
Things I have already replaced to fix thix this issue:
ICM, MAP, CPS, TPS, ECT, IAT, checked fuel pressure and fuel pressure regulator. New vacuum lines, no vacuum leaks
What am I missing? The only thing showing up on scan is an o2 sensor.
have the same problem?
