OK, my car (87 2.8 firebird) is STILL having a problem with starting. This is driving me nuts. I just checked my fuel pressure and it reads 45 with key turned on and 40 with motor running. I turn it off and the pressure slowly decreases. I've replaced the fuel pressure regulator, coolant temp sensor, fuel pump relay, spark plugs, reset timing to 10*. I also got a error code 54 couple of days ago but car is still running. Do i need to check the injectors themselves? How do you do this? Any other ideas? It also idles a little erratically (almost a little too low it sounds like). Might be time to pay someone to take a look.
