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. See Fig 1. See ENGINE CHECK CONNECTOR LOCATION table.
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 poor fuel pump ground. See WIRING DIAGRAMS article.
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 in this article. For more information on wiring, see the WIRING DIAGRAMS article in this section.
