2000 4.7 limited no spark
I have a 2000 grand cherokee limited. The alternator went out so we replaced it, which lead to the TCM and PCM being replaced. Now i have fuel in the rails, but intermittently it will throw code P 1389. Is there a ignition control module that could have blow and if so where is it? I am replacing the ASD relay and will update the thread if that fixes the issue. Any help on how to get the spark would be greatly appreciated.

with all the work you have done i am guessing you have checked to make sure power is going to the coil? also, does the ASD click when you turn the key to start it?
