Hi Dave,I would guess there is nothing wrong with the ECU, it has just lost sync. You need the diagnostics to read the EMS code in the engine ECU and then enter it manually into the BECM.
It won't start unless the codes are the same.
Also stop calling it a Jeep.
Thanks for your constructive comments ... really big of you and hilarious ... hope you feel good about them. I’m glad there were other folks on this forum who were actually willing to help.I had to open this thread to find out what "limo mode" was - my P38A never had that option.
"The Jeep wouldn't start"!!!! What an insult!
