Why wont my 1989 oldsmobile start
I have a 1989 eighty eight oldsmobile with a 3800 engine. We can not figure out what is wrong with it. It sat for awhile then went to start it and would only start while pumping gas pedal. Would let it run and warm up and drive it around but once I shut it off it would not start again. Anyways it will not start at all now. Had battery checked it was good. Replaced alternator, fuel filter, fuel injectors, spark plugs and wires, new oil filter and oil change, air filter, new ignition coil pack. The car will turn over but will not start at all we are stumped. The fuel pump is turning on when key is turned over and fuel pressure looks good when coming out of the fuel rail. Please if anyone has any ideas let me know. Thanks in advance
