Test Notes

NOTE: You should enter this Pinpoint Test only when directed here.

REMEMBER: This Pinpoint Test is intended to diagnose the following:

- Chassis Components

- Engine Vacuum

- Fuel Pressure

- Fuel Filter

- Fuel Return

- Fuel Supply

- Fuel Injector

CAUTION: Use care to prevent combustion from fuel spillage. No smoking, open flames or any kind of arcing.

WARNING: The fuel system remains under high pressure even when the engine is not running. To avoid injury or fire, release the fuel pressure from the fuel system before disconnecting any fuel line. To release the pressure from the system perform the following:

- Connect the Rotunda Fuel Pressure Testing Kit (014-00447) or equivalent at the schrader valve located on the fuel rail. Testing kit valve should be closed.

- Gradually open the testing kit valve to relieve fuel pressure in the vehicle fuel system and drain the fuel into a suitable container or return it to the fuel tank.

- To avoid unnecessary fuel spillage and fire hazard any time fuel lines are disconnected, the ignition switch should be in the "Off" position unless fuel pump operation is required for test purposes.
