1) Some older ISB engines use a different original equipment manufacturer (OEM) interface
connector than illustrated.
2) Fault Code 377 can be caused by a stuck fuel pump relay. If voltage is detected at pin 7
of the fuel pump connector, with the keyswitch in the OFF position, check for a faulty fuel
pump relay.
