HOw to Starting 1999 ford expedition without key?

SOURCE: A loud sound shortly after starting my car

I'm guessing that you Expedition has been making this noise probably since you've had it? Even if it hasn't, I think I can bring you some comfort. If you could pinpoint where the noise was coming from under the hood, would you say that it's somewhere over on the passenger side? My dad owns a 1998 Ford Eddie Bauer Expedition, and we noticed a loud noise with the same habits as what you're describing. Come to find out, there is an air compressor under the hood, I can't remember exactly what it's for, but the sound that I believe you're hearing is the compressor filling up with air and then shutting off once the proper amount of pressure is reached. You might try popping the hood to try to locate the exact place that it's coming from, but I can tell you that it's probably a 99% chance that when you find your noise, you'll find the compressor I'm referring to. Hope this proves to solve your issue and helps to ease your worries. Have a wonderful evening!

Hi and welcome to FixYa,

To my knowledge, you assumption is correct on most designs. That wire should go to the ignition switch and will be hot when key is in START. However, same wire often would be connected first to a relay that is interlocked with some conditions/status other then key to START. They would be:

• automatic transmission should be in neutral/park with light indicated;
• alarm/security/immobilizer is inactive/OFF.

It should be on the back of the transmission near where the driveshaft goes in. Buy a new one, jack up your truck and look for the old one on the back of the transmission
