2000 Expedition wouldn't start?

[Abraxxas]

Hello everyone! This is my first post here, seems to be alot of good advice so wanted to ask everyone a question. I did try to search the forums a bit to see if my question was answered first, but alas no luck.

The other day my expedition would not start. Funny thing was that the oil pressure/engine coolant light was on and the odometer had nothing but ----- on the display. These two things were on even though there was no key in the ignition. The expedition would turn over trying to start, but wouldn't. This was first thing in the morning, the truck had sat all night, so it wasn't hot.

I called two Ford delerships and talked with the maintenance department at both locations. The first place asked if the "Theft" light was on, I said no, which it wasn't. Then he said there may be rodent problems, but he wasn't for sure and that I should have it towed in to have it looked at. The second shop didn't know either and said i should do the same.

Well I looked for chewed wires, checked fuses, checked water level in radiator tank, and oil. My inspection turned up nothing. I gave up for the time being and went to bed. Later that day when i got up I went to check again, not wanting to give up and to my surprise the lights were off and truck was able to start. Since then its been about a week with no problems.(Thankfully) Though I am worried that I may be out and about and same thing would happen again leaving me and family stranded.

If anyone has helpful info it would be greatly appreciated....Thanks

I had the same thing with my 2000 expy. I took it to the dealership three times. First time they said it was not reproduceable. Second trip they claimed that the fuel pump and lines needed to be replaced. Cost me over $1200 but it ran real good for a day or two. It still had the no start up problem. Took it back the third time and they claimed it could be just about anything electrical with the starting system since it tossed no codes. I bought a new '05 EB and that fixed the problem...

Thanks for the input maddog, still to this date I haven't had the same problem. Been thinking of getting rid of it myself for something a bit better on gas since gas is outrageous now days.

it sounds like you need a gem moduel. After reading this fourm it seems to be a common problem. The windshield leaks water gets into the gem mod and causes all sorts of problems. you won't even know the windshield leaks. Ijust took mine to a dealer $1000.00 plus for mod and fuse box. Ford said I had to get a new windshield too. I said I would think about it and wouldn't you know my windshield mysteriously broke in the middle of the night so insurance took care of it. After gem mod dried out no more prob. Went from $1000.00 plus to $000
