I have a 2000 expedition that started acting up over the weekend. First, it would start but not stay on, I had to use both feet to keep it on. It would turn off and I had to turn the ignition to restart it. I spoke to a friend who had the same problem and, he told me it was the idler air control valve. The next morning I was going to turn it on and at first it won't even turn over, then I tried again and it did. I had to use both legs again to get to the parts store. when I got there I replaced the idler air contol valve. When I went to start it, it did nothing!! I mean nothing, the lights on the dash would come on and so would the radio but as some as I tried turning the key it all would turn off and the truck would not do anything. I took the battery and had it tested. It tested GOOD.I had the truck towed home, the tow truck drive said it was the starter, I took the starter off yesterday and had it tested, it tested GOOD. I've checked ALL the fuses inside and out they are all GOOD. I checked the fusable link on the battery terminal, GOOD. But the truck will not turn over nor start, NOT a single noise. I do hear the relay clicking when I turn the key.
PLEASE CAN SOMEONE HELP!!! This is my only means of transportation.

 

It could still be the starter solenoid, mounted under a plastic cover on the passenger side of the cowl.

 

Thanks for the reply Paul. If it was the starter solenoid. I should be able to jump the solenoid and the truck shoud try to start. It does not even do that. Please advise. I could see the solenoid being a problem because I had to start it a few times and I did smell something, but I would think I would be able to jump the solenoid and get it to crank over.

 

Here's a question to the board: If a PATS key goes bad, will the engine crank, or will the starter circuit be completely disabled? Firzout, try your other ignition key and see if it makes a difference.

 

I already did that. The result was the same.

 

Paul, I went and replaced the solenoid anyway, had nothing to lose. Guess what it WORKS!!! THANK YOU SO MUCH!!

 

Hey, I'm good. What can I tell you?

 

I had my solenoid fail at the dealer while getting warranty service just prior to warranty expiration. That would be 36K miles. I was fortunate. Why does Ford use this part?

 

And this week's $5,000 troubleshooting award goes to.... (*insert drumroll*)

PaulC!

Please pick up your check at my house by 3pm today.
