1996 lt1 camaro rough start and when it does start it idles rough until it dies
Hi there I have a 1996 lt1 Camaro that I have been trying to fix for about a year now and still no luck. It is an automatic with CAI and no cats, flowmaster exhaust. Here are things I have tried:
Fuel pump (went out 2 years ago replaced it and it fixed my problem)
Fuel filter
FPR
Fuel injectors
Spark plugs
Plug wires
ICM
Coil
battery
Alternator
starter (and cables that go to battery)
Distributor cap and rotor (water pump too)
Crankshaft position sensor
Any ideas would be greatly appreciated or maybe a new checklist to start from here.
Thanks

Checked the fuel pressure? Scanned for codes? Checked for vacuum leaks? Any difference in the results whether the engine is hot or cold?

Fuel pressure is normal. i have tried the key lock bypass recently and that did not work. So I'm thinking I am having a issue with the fuel getting cut off as I start it. I bought a theft deterrent relay and was going to replace it but I can't seem to find it anywhere under my dash. It's a 96 so idk if it's somewhere else but every search I do has no luck. Do you know where this is? Or is there a bypass I should be doing so the fuel cut off issue isn't happening anymore? Thanks

Update: found the theft deterrent relay and replaced and it fired up but still idles rough! It stayed running for a minute or two and then died. It seems to start every time now but can't keep it running for more than a couple minutes.

is your fuel pressure holding steady during the time it does run?
what FP reading do you get?
OBD 2 code readers are cheap, is the CEL light on?
