Fuel Pump Quick Test

Turn ignition on, with engine off. Place jumper wire across +B and FP terminals of engine check connector in engine compartment. Refer to the ENGINE CHECK CONNECTOR LOCATION table. See Fig 1
Listen for fuel pump running sound. Feel for pressure in fuel line between filter and fuel rail. Turn ignition off. Remove jumper wire. If fuel pump sound was present and fuel hose showed pressure, go to FUEL SYSTEM PRESSURE TEST .
If no pressure or fuel pump sound was present, connect a jumper wire from battery source to FP terminal of engine check connector.
If fuel pump does not run or no fuel pressure is felt in line, check for defective fuel pump. Check for open circuit between engine check connector and fuel pump or for poor fuel pump ground. See appropriate wiring diagram in WIRING DIAGRAMS article in this section in this section.
NOTE: All models use in-tank fuel pump. Fuel pump contains internal relief valve and check valve.
If fuel pump ran after battery source was connected to FP terminal in step 3), check EFI main relay and related wiring. Also check EFI and IGN fuses. See FUEL PUMP CONTROL CIRCUIT . For more information on wiring, see appropriate wiring diagram in WIRING DIAGRAMS article in this section.
