2003 Excursion Limited

Installed a single file (no switch) F5. Contacts are clean chip is installed correctly (not my first install). Get everything back together and turn the key on. Normal Theft then after a few seconds the theft light flashes rapidly. The truck will crank over but no attempt to start. After 30-45 second the theft light will go out but no change

I have found a few similar issues with the recommendation to relearn the key to the PATS system and that has not worked.

Any suggestions? Diane and Jody are out of the office.

Diane said Jody was going to check it Monday and if its not right he is going to send out another chip Monday and I can send this chip back later. I hope that is all it is. I've got about 4 hours into this chip and I can't bill any of them!

I have a 2003 Mustang GT. Had the same problem.....turn over and and over but no crank, THEFT light flashing very fast. Took it to dealer, they couldnt find anything wrong with anything....PATS was good or whatever..
Finally figured out that when I tried to start it with the steering wheel tilted "UP", it was stretching some connection in there, making the Security Theft thing do its thing.
Try tilting the wheel down and give it a spin....that's what i've been doing since 2003:blah:

Yeah I have tried that key on/off procedure for the PATS key relearn but no go! I was hoping it was that simple!

The chip has PATS enabled so we're doing some testing. I don't have this issue with my EX so we're just as puzzled.

Tim, you'll have another chip coming tomorrow to see if it may be a flakey chip.

Thanks Diane! I look forward to getting it and trying it!

I forgot about that, I did that on my excursion.
Wait! Wait! your KIDDING ME!! to disable the system all you need to do it unplug the module? Did a 2 year old design this anti theft system? No wonder so many Fords get stolen!

Tell me more about this possibility if the chip won't work. PM it if you please as to not tell the scum bags that might use it to steal our trucks!

Here is an update! Jody and Diane sent the chip out 2nd Day Air and got it Wednesday:rockwoot: (very nice thank you!). Customer came in today I slapped the chip in there and its good to go! Theft acts normal, truck starts and run great!

So I just have to send the first chip back via the return label they sent with the second chip! Jody and Diane WELL DONE!! You took all needed steps to solve the situation and I thank you!
