System Integrity Check

• 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. On vehicles with 2 fuel tanks, check both tanks.

If any fault is detected, repair as necessary. If system checks are okay, go to next step.
