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 upper (tripped) position.
Ensure battery is fully charged and fuel-related fuses are okay.
Check fuel tank contents and fuel gauge accuracy. If system checks are okay, go to CHECK FUEL PRESSURE.
