All euro software calibrations have the immobilizer software embedded in them. Even if turned off, it turns itself back on. The only way around this that I have found that works is to program ecm with USA software and then disable skim function.
Thanks for your quick help on my UK Jeep ECU/Immobilser problem. Can I send it to you for programming. I have tried twice so far with All Computer Resources, but it hasn’t worked.
If so pleased give me address and approx. cost for fix, and confirm what I need to send.

Of course you can!! Please sends me an email to [email protected] with your name and address and I will send you an order number on Monday. The 3rd time will be the charm!
Thanks Mark for reprogramming this unit. However I still have the same problem - turning over but not starting. There is good fuel pressure. I made sure the key shroud was disconnected before installing. Do I need to leave the ECU in for a while before starting in case the software needs to load?
Are there any other tests/diagnosis type things I can do to confirm I am on the right track about it being immobiliser related?
