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 320-370 kPa (3.3-3.8 kgf/cm² , 47-54 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.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
