2005 Explorer XLT
Hello All,

I have a 2005 Explorer XLT with the regular 4.0L (not the flex fuel) with only 38K on the clock. About a few weeks ago, the truck died while driving. I towed the car home and replaced the fuel pump with a napa part. All was fine for 3 days, when the same thing happened again. Took the truck to an authorized ford dealership ( I know, last resort) and they claimed the napa part was drawing too much current and popping the fuse in the power distribution box. A week and a half later got the truck back all fine and dandy. 2 days later, the same exact thing happened while driving (after I went to a car wash). Tried replacing the fuse 3 times, but each time the fuse blew as soon as i turned the ignition. I am fine with doing regular work on a car, but electrical and finding shorts (which i am very sure it is) is definitely something I have ZERO experience with. Anyone on this site have any clue as to what it could be? It baffles me that the truck could be fine for a few days and have the same problem re-occur. Any help would be greatly appreciated. (PS the dealership said they checked for shorts)
 






Is it possible the harness got pinched somewhere when the tank was put back in?
 






possible yes i suppose. I suspect a short just due to the nature and repetitiveness of the problem. I hate going to dealerships for repairs but this was my only option. This is the second time its broke down on me and now the second fuel pump (this one is OEM ford). I think the mechanics are taking me for a ride, but i dont have any other option as I have no experience with wiring. I just want some good input on where to start looking from this forum.
 






If it were mine, I would start by looking under the fuse block for the short. Then i'd just start following the wires starting from the tank. Probably wont be fun. I suppose it's possible the relay could be shorting out, but I have never seen it happen before in my 15ish years as a used car mechanic. I also have not heard this being a common problem yet, so there's nothing I could find about it.
