Fuel Injection Supply Manifold and Fuel Injectors
WARNING: This page is about a different car, the 2003 Ford Econoline and 2003 Ford E450 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the fuel pump relay from the power distribution box.
- Construct a jumper wire from 152 mm (6 inches) of 18 gauge wire and two spade terminal ends.
- Jumper the fuel pump relay circuit from Socket 87 to Socket 30.
- Remove the jumper wire.
- Install the fuel pump relay into the power distribution box.
- Check the spring lock coupling and the fuel injection supply manifold to fuel injector connections for leaks, using the combustible gas detector.
- If a leak is detected, verify the connection is engaged properly, then retest.
- If the leak remains, repair as necessary and retest.
NOTE:
After the vehicle has soaked for several hours, a very slight natural gas smell may emanate from within the intake manifold and intake air system. This is normal, as the fuel injectors leak down from the fuel injection supply manifold to the intake manifold over several hours.
