Does your car crank?
Is your car equipped with a factory immobilize system? What color is your key?
Did you install new or used powertrain module?
What is going on now, are the codes active or they were before replacement of the parts?

just wanted to see if you have run across this problem before. yes 12v we put in a new engine wiring harness coil and pcm it still has the same codes . I was just trying to find any other ideas thanks

Expert:  Vladgmru replied 9 years ago.
I have met the same problem on a Grand Cherokee.
The problem was a bad pin inside a PCM connector.
I think I can help you, but it seems you are not interested in that.
Have a good time.

do you think i would have a bad pin inside a new connector wiring? look on line several people have the some problem . in my 25 year of experience as a tech, I have never seem this before thank for you time
Expert:  Vladgmru replied 9 years ago.
No, I think new connector is OK.
I will search it on IATN and let you know if I find something.
Expert:  Vladgmru replied 9 years ago.
Were PCM, ignition coil and engine harness replaced at the same time or you have tried new PCM with the old coil?An old coil could kill new PCM.
Does BCM see ignition switch MUX voltage ( correct ignition position )?
If not, BCM tells to PCM about it and PCM might not command the coils on.
Customer: replied 9 years ago.

Had replace pcm twice,third time pcm and coil together repair wire car ran for 1,000 miles this time put all in new pcm and coil and new harness. car would not start has same codes . Went out to start car it starts now .Will check bcm but now car is running any other way to double check problem. Thank


Expert:  Vladgmru replied 9 years ago.
Let me know your results about "Ignition position" on BCM data, at the moment the car wouldn't start.
