LT1 Start Issue Hello, I have a 94 Camaro with LT1. I rebuilt the engine with a cc503 cam, head work, etc etc. The car sat for a few years but I recently started fixing it up. I replaced the opti, plugs, wires, coil, ICM, MAF, both O2 sensors. I have 2 issues, first one is sometimes it starts and sometimes it doesn't and I drain the battery trying. I checked all voltages from shoebox and everything reads right. It'll turn over and seem like it'll catch but won't start. When I connect the battery charger to it and try it'll just turn over with zero fire.
The second issue is when it does start, it'll run great up until the temperature gauge starts to move (160F) and it'll start stumbling and sometimes stall out like it is running way to rich. Anyone have this issues before?

How's your fuel pressure? It could be your Omni spark distributor if you haven't chan I'm having the same problem building if I spray carb and choke cleaner in the intake it'll start up and run for a little while and then die. I have great fuel pressure but my buddy who is one of the smartest people I know said that it takes less spark to start on the carb and choke cleaner because of lower ignition temp.
