Hello everyone and thanks in advance for your help! I post this in another section hoping for find some answers on problems I'm having with my Excursion.... Please read on to my reply lol
Hello Everyone!! I noticed this post trying to search for answers for a very similar issue Eric had......... minus the aftermark alarm. And hoping for more insight or direction.
I have a 2004 Excursion 6.0 with 242k.... have owned the vehicle a week... never once had a problem starting it.
Took a trip to the city museum, drove back home to drop my sister off at her house, left her drive way and about 10 seconds later my diesel just shut off(no I didnt turn the vehicle off while at her house so no delayed shut off). I go to try and turn the vehicle back on to start and the THEFT light is blinking rapidly. Glow ignitor just stays on for an extended period of time but no ability to start....
Now I've tried the whole reset thing,,, wait till the light frequency slows down,, turn off,,, wait,,, put key in,, etc,,,,,,, I've tried the leave the negative cable off for hours and hours,,,,, reconnect,,, and still a fast THEFT light.....checked the battery voltage, gtg,,,,,,,,,, I've checked all fuses,,,, switched pcm relay,,, etc,,, no go! I even tried connecting a code snatcher up and it refuses to connect and pull the vehicle info.... really!@#? lol
So I'm getting a PATS theft signal..... but the problem originated while driving and shut off so it cant be by design,, yet it now defaults to a PATS indicator... I've done my research and have also heard the PCM may be the culprit.
Any help or suggestions? I've seen this issue around and this seems to be the best place to get the answers for everyone and so when people have this problem in the future they can find this post. lol
I dont know if this will help or not. Same thing happened to me with an F150. Ended up the key was dropped recently and the key was bad. I tried my spare key and worked just fine. So if you have another key try it. Its worth a shot anyways. Good luck
I had the same issue with my 03 F150, would crank but not start with the theft light flashing...
The problem turned out to be a bad ECM relay that was not powering up the ECM
Considering you cant pull the codes, i'd be checking your fuses over and also you might try swapping the relay that powers your PCM or even the PATS module (if it has its own relay)
Edit: Just reread where you checked all fuses and swapped the PCM relay. Not sure if there are any other relays that might be of issue..
2nd edit: I dont think its a bad key issue since it died on you. I could be wrong but I think that once the PATS has verified the key, it no longer controls anything. If that module loses power on the other hand, i think it could cause an issue.
