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 on all models, 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 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 in this article. For more information on wiring, see WIRING DIAGRAMS in this section.
