Relieve the fuel pressure.

Disconnect the quick-connect fitting. Attach the fuel pressure gauge set and the fuel gauge assy.

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 the fuel pump circuit troubleshooting.

Read the fuel pressure gauge. The pressure should be 330−370 kPa (3.3−3.8 kgf/cm ² , 47−54 psi).
- If the pressure is OK, the test is complete.
- If the pressure is out of specification, replace the fuel pressure regulator and the fuel filter, then recheck the fuel pressure.
