I'm having the same problem...
It is inside the fuel tank.
probably the fuse or relay on the fuse block is bad , find and replace the fuse or relay and trunk and fuel door should there may be two separate fuses ,
Pry bar and a hammer
One reason a 1998 Cadillac Deville would cut off while driving could be the fuel pump or the car is out of fuel. Another reason could be the spark plugs.
On a 1998 Ford Explorer 4 door : The fuel filter is underneath the vehicle , below the drivers door , mounted on the frame rail
Between the rear wheels or on the rear left side near the passenger door.
Fuel filter 1986 Cad Deville It is under the car, I believe under the drivers side of the car, right below the front door mounted to the floor on the bottom side on brackets. If not there under passenger door. Get a flash light & look under car. Jack up vehicle, you will see it disconect it on both sides of the filter with the right size open end wrench. A little fuel will leak out. When you disconnect it keep it parallel with the car to minimize fuel spilling, easy job. It is very close to door panel. Not far under car, less that a foot from door. If your car has an electric fuel pump it is best to remove the fuse that services the fuel pump and start the engine. Let it run until it dies to remove the pressure from the fuel system.
I have a 95. I find a little wd40 once a month helps out alot. check valet button in glove box.valet button deactivates fuel door realease.
No, tank has to be removed.
yes there is- its called walking back to the fuel door and opening it like any other car.
If the fuel door won't close, it may be due to a misalignment or obstruction, such as dirt or debris in the hinge or latch area. The locking mechanism might be malfunctioning, or there could be an issue with the fuel door release cable. Additionally, if the fuel tank is overfilled, it could prevent the door from closing properly. Checking for these issues can help identify the cause and resolve it.
your door sensor pin may be broke
