Hi Everyone im new and have a problem with my 99 Ford expedition everything was running fine until one day i was sitting in the parking lot with truck running and i shut it off when i went to start it it started and when i put it in gear it died i found the fuse for the fuel pump blown i replaced it and as soon as i put it in gear it blew again so i figured my fuel pump was bad so i went and replaced the fuel pump and after i got it done i fired it up and it will sit there and idle with no problem until you put it in gear it blows the fuel pump fuse any ideas would be greatly appreciated cause this is my only vehicle i have and i need to get to work
thanks eveyone

I don't know if you had a chance to check. When you place the selector in gear the engine probably moves some and it could possibly be contacting a worn through wire causing a short in a completely unrelated circuit. Might be a good idea to look closely for any wires that get too close to the engine when it moves. Does it happen in reverse too?

Thanks for the reply im suspecting a wire grounding some where i was told to look in steering column maybe when i shift into gear it rubs it will idle good until i put it in gear and step on gas then it will blow the fuse

It idles well but I was thinking, aside from a dead short associated with whatever metal pieces is moving when selecting a gear with full swing, park to reverse, that maybe the fuel filter is plugged and that forces the pump to push fuel through a blockage harder and therefore the fuse blows as amps increase. Far fetched idea...happens on Saturn's a lot especially when below zero temperatures and you hard accelerate.
