Ok..It took me a few but I think I have translated the Abonics in the post and extracted the situation.
Next time you go to start it, turn the key on for like 3 seconds, but don't crank it. Promptly repeat this 3 - 5 times,
then start it. Does it fire right up or does it stutter ("studders")? If no change, then please post the code(s) you pulled from the ECM. If it starts up fine, then the bad part can be summed up with two words. Never, ever buy
any parts until you have
proven that you have a bad one needing replacement.
