Bought an 85 Cougar, test drove and it ran fine. Now it’s failing to start. It will run if fuel is poured into the 4th throttle body. The fuel pump works when the relay is jumped but still won’t run. Disconnecting the line from the throttle body and jumping the relay produces fuel so I know the line isn’t plugged. I’ve replaced the fuel pump relay, eec, and fuel filter so far. Tried a new ignition switch as well. Any suggestions?
Check ECM Fuse and check for injector pulse. My guess is the injector is not firing.
