02 Lincoln Navigator Wiring issue.
I have a 2002 Lincoln navigator I bought the vehicle from a used car dealer. At the time I didn't notice and I don't think they noticed that the main wires that run to the back of the vehicle down the back side of the wheel well were hanging down and were being rubbed in half by the tire. The truck started dying when the wheel would cut into the frame. Since that has happened the place where I bought it from put the wires back together, but it still didn't start. I took it to ford had it diagnosed and had a new pcm put in it. Ran right for a couple of days and then started acting funny, oil pressure light coming on and overdrive light blinking and check engine light on and running funny. 7 codes were coming up all sensors saying check connector and wiring. When I would turn it off it would not start for 10-20 min. After that it would start and run fine. Now it’s back to where it will start after a certain period of time but the lights are not going off and it won’t run long enough for me to drive it to a shop. Any advice would be helpful and a ballpark price to fix.
