Special Tools Required

Relieve the fuel pressure (see FUEL PRESSURE RELIEVING ).
Attach the fuel pressure gauge set and the fuel pressure gauge.

Start the engine, and let it idle.
- If the engine starts, go to step 5.
- If the engine does not start, go to step 4.
Check to see if the fuel pump is running: Listen to the fuel filler port with the fuel fill cap removed. The fuel pump should run for 2 seconds when the ignition switch is first turned on.
- If the pump runs, go to step 5.
- If the pump does not run, do FUEL PUMP CIRCUIT TROUBLESHOOTING .
Read the fuel pressure gauge. The pressure should be 390-440 kPa (4.0-4.5 kgf/cm² , 57-64 psi).
- If the pressure is OK, the test is complete.
- If the pressure is out of specification, replace the fuel pressure regulator (see FUEL PRESSURE REGULATOR REPLACEMENT ) and the fuel filter (see FUEL FILTER REPLACEMENT ), then recheck the fuel pressure.
