Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Good evening and welcome to JustAnswer!!
If you have a misfire on #1 and #4 and the coil is not sending a spark on those cylinders then you need to disconnect the coil and since the ASD has a constant 12v feed then you will need to check the coil driver circuit from the PCM by connecting your test light to the positive post and probe the driver wires and see if it flashes.. You stated you connected to ground which is why I need for you to test it correctly and let me know what you find. I suspect that since you have a new coil and it's doing the same then then your PCM coil drivers and bad and the PCM will need to be replaced..
I hope this helps,
I see this question is still open.. Don't forget to rate so I'm compensated for my time..
Have a greatday,
If the test light didn't light up bright in the coil driver circuits from the PCM then the PCM is bad and it will need to be replaced..
