Hey guys, I was a member years ago and y'all helped me with my truck and saved me a lot of money in the long run so now I'm searching for help for my grandparents. They have a 2007 Expedition, with all the features, (can't remember what model but I'll update later, navi, leather and all that stuff) After they got gas today they drove home and stopped at the mailbox, took the key out of the ignition got the mail then put it back in and tried to start it. Nothing happened, didn't barely turn over, didn't click it was just quiet. Battery power was in tact though so I know it's not that, but just in case I disconnected it (and hopefully restarting the alarm just in case it was that but it wasn't that either). I didn't hear the fuel lines or anything. I thought it might be a computer issue, alarm kill switch issue or something like that. Hopefully y'all might have an idea before we waste a bunch of money at a mechanic. thanks guys!!
We just got our 2007 Ford Expedition Limited back from the Ford dealer; they had it in the shop from 14 Sep - 11 Oct 10!!! The mechanics were idiots. The initial problem was that the truck would crank, but not start. After about 3 weeks of "checking everything" they decided to replace the engine control module. It didn't fix the problem. They ended up flying in a Ford tech; he couldn't figure it out. They flew in ANOTHER Ford tech and he determined that it was most likely the fuel pump. The dropped the gas tank and found that the fuel pump had melted to nothing and the cabling going in and out stretching about 1-1/2 foot away had melted. Per the Ford tech; "You're lucky you had a full tank of gas, otherwise the truck probably would have exploded." When asked what caused the failure, their response; "We have no idea". They also replaced the control module; which had also failed. They socked me with a $1310 bill to replace the fuel pump. The control module was replaced under warranty to "help me out" after the fuel pump bill. I'm trying to find out what exactly the engine control module controls. My opinion is that it was most likely what caused the failure of the fuel pump. There were other indications of electrical system failure such as my wife plugged her cell phone charger in the outlet and it turned the A/C off - this was fixed when the control module was swapped.
