Can anyone tell me what the difference is between a 2S and 3S body type for a 1990 Mustang Gt?
I have a 1990 Mustang Gt 5.0 that I just put a new motor trans and harness. Fuel pump will not prime. 12V to pump and it will run, Checked all ground connections, changed fp relay. only getting power to relay.
Also changed Ignition control switch,
