I guess I’ll start this off with a long story short kinda intro.
I bought my 2004 Expedition about 5 weeks ago from a good friend of my wife’s. It was her fathers, Great man as he now rest in peace loving the good ol’ life within the afterlife. But boy howdy, that man did not take care of his vehicles. At multiple times when trying to clean it when I first got it, had to literally take mallet and chisel(s) yes plural because one shattered, Haha…To only the lord knows what monstrosity of growth was in those carpets. That being said, the truck was in bad shape. Not to the short part of the story in the long head scratching wonder that is now my brain.
Few days back my truck wouldn’t start. Did all the troubleshooting. The battery was good I just purchased that a week ago, all relays and fuses were good and then I noticed some green plastic pieces on the driver side floorboard, those kinda “Hey I’ve seen things that look like that before” pieces of plastic. Well they were broken pieces of the wire harness connector that just so happened to be inside the steering column that’s for the PATS system immobilizer. The4 conductor harness under the module around the ignition. So I grabbed a couple 2 conductor speaker wire from an older Bluetooth garage speaker, used the plastic connectors from both as well the wire leads from them and tied those into the 4 conductor connector for the immobilizer module. Truck still wouldn’t start. I checked the fuse box and fuse 28 (the PCM relay coil and SecuriLock transceiver) was blown. I replaced it and then turned the ignition over. The truck started, Angels sang and Bobs your uncle.
But then today I went to start the truck and nothing. Well nothing accept the typical door open beeps and dash lights coming on… BUT now the Anti theft light on the dashboard near the windshield was flashing extremely flash. The battery is still good, only week old. The fuse is NOT blown, starter is working fine. I checked the relay as well as jumped the terminals in the fuse box and it cracks that way.
So… Is my key going bad possibly. Or the PATS module itself maybe?
I tried resetting the theft system with the key in the door trick then with the ignition and still, nothing?
Other then taking it to a dealer to check the PCM module itself or pay hundred to have new keys made, I figured I’d test the waters here and see if anyone knows what’s up, might have suggestions to try I may not have.
Any input is helpful, thanks all
