Question about 1991 Pontiac Grand Am
I changed cranksensor,ecm,ignition control module,fuel pump,fuel pump relay, the fuel pump will run when i jump the relay,I tried to start the car this way but fuel injection unit will not spray gas, if i ground the wire going to the ecm for the fuel injection it will open and spray,the car will fire up and run by spraying starter fluid so I believe something is preventing power going to the fuel pump relay coil, I checked it with a meter and ther is no power when key is turned on,and preventing the fuel injection from opening any insight on what to test or what may cause this would be helpfull
Look for a bad fuse or relay. If both check out, most likely an ECM problem
