Fuel Pump Operation

Install jumper wire between +B and FP terminals of engine check connector. See Fig 1-7. Turn ignition on.
Listen for fuel pump operating sound and feel for pressure in fuel line near the fuel filter. Turn ignition off. Remove jumper wire. If fuel pump operates, check fuel pressure. See FUEL PRESSURE under FUEL SYSTEM.
If fuel pump does not operate, connect a jumper wire from battery source to FP terminal of engine check connector. If fuel pump operates, the EFI main relay, circuit opening relay or fuel pump relay may be defective. For explanation of relay operation, see FUEL PUMP CONTROL CIRCUIT under FUEL SYSTEM.
If relays are okay, check wiring circuit and fuses. If fuel pump does not operate, check for defective fuel pump or open circuit between engine check connector and fuel pump, defective fuel pump ground or fuses. See appropriate wiring diagram in WIRING DIAGRAMS article in this section.
