Is the Fuel Inlet Strainer plugged?
Yes → Replace the Fuel Pump Inlet Strainer.
→ Replace the Fuel Pump Module.
No
4 Fuel pressure gauge still installed.
NOTE: Fuel pressure specification is 400 KPa +/- 34 KPa (58 psi +/- 5 psi).
Ensure the fuel pressure is at maximum pressure.
Monitor the fuel pressure gauge for a minimum of 5 minutes.
NOTE: The pressure should not fall below 241 KPa (35 psi)
Does the fuel pressure gauge fall below the above specification?
Yes → Go To 5
→ Check the fuel for contaminants.
No
5 NOTE: Before continuing visually and physically inspect the fuel delivery
system for external leaks or damage. Repair /replace as necessary.
Turn the ignition off.
