Question about Lincoln Navigator
In this situation, we start with the easy solutions which is to check each fuse in the fuse box is installed tight. Also with the engine on, wiggle each fuse and see if it affects engine in any way. If it does the fuse may not be tight in its socket. Do the same with the relays located in underer the hood in a platic box at the driver's side. Make sure they are tight in their socket and wiggle them with the engine running. Do the same for any wiriing harness connections you see. Wear gloves, no jewelry, or loose clothing when you do this. If everything is okay, then it is most likely your fuel filter. You can do fuel pressure test to verify you are getting enough pressure.
To change the fuel filter, you will either have to disconnect the fuel pump relay or the fuel pump harness to depressurize the fuel system. Under the driver side door underneath the car, you will find the fuel pump clamped to the body. Remove the mouning blots and unscrew the clips from the fuel line. Keep note of the arrow direction and replace with a new fuel pump. Thanks for using Fixya.
