Here's on for you,91 RS 3.1 litre crossfire injection camaro. I went out when day to start it up and its would turn over but not start, cleaned up the plugs and went on my way, until it died a day later. Did a full tuneup, plugs,wires,cap,rotor. Still dead no fuel pressure. Replaced the fuel filter it was pretty clogged up but same issue, replaced the fuel pump and the car began to run after replacing the fuel pump fuse, the one on the passenger side in the engine compartment. The car runs but very poorly now, it wont accelerate like it used to. I checked the timing with the est bypass connector disconnected it was correct but noticed that when this is reconnected there is no change in the timing at idle. Heres the best part, the car idles smoothly but, disconnecting the spark plug wires from the entire passenger side, all 3 caused it to idle smoothly as though it is running on all 6. Good spark to all spark plugs has been checked and double checked, the injectors on that side all are recieving the pulsed power without issue. If you remove any of the wires on the drvers side it runs horribly and is missing. No error codes using the diagnostic terminal and the check engine light. Is there another way to test the injectors, any ideas?
