System Integrity Check
CAUTION:
Inspect fuel system for leaks and damage before testing fuel pump.
Perform the following checks:
- Visually inspect fuel system (fuel lines, filter, pump, injectors, pressure regulator, etc.).
- Ensure Inertia Fuel Shutoff (IFS) switch reset button is not in the up (tripped) position.
- Ensure battery is fully charged and fuel-related fuses are okay.
- Check fuel tank contents and fuel gauge accuracy. On vehicles with 2 fuel tanks, check both tanks. If any fault is detected, repair as necessary. If system checks are okay, go to FUEL PRESSURE CHECK .
