1. Do not smoke.
2. Wear approved safety glasses.
3. Have a Class B dry chemical fire extinguisher nearby.
4. With ignition off, release fuel tank filler cap.
5. Disable the fuel pump. Follow the manufacturer’s recommended procedure.
a. Some vehicles may have two fuel pumps. Both pumps must be disabled.
b. A common method of disabling the fuel pump is to remove the fuel pump fuse.
c. On some vehicles, removing the fuse also disables the fuel injectors or ignition system, so another method of
disabling the pump must be used.
d. On some vehicles, the fuel pump can be disabled by disconnecting the fuel pump wiring harness.
e. On Ford vehicles, equipped with an inertia switch, check that the switch has not been tripped. The inertia switch is
usually located in the trunk.
6. Turn on the ignition and start the engine. If engine will not start, check ignition system for spark. If no spark is present,
refer to the vehicle service manual for No Start Diagnostics.
7. Run the engine until it stalls.
8. Try to restart the engine for 3 to 5 seconds. For some Ford/Mercury/Lincoln vehicles with inertia-switch pressure relief,
engage the starter for 15 seconds to relieve fuel pressure.
9. Turn ignition off.
