im new and i hope i posted this in the right thread..
so my 01 3.5L aurora was basically given to me when it broke down about a year ago. Unfortunately i didnt get the chance to look at until recently. The problem started off with the car cranking but not starting. I found out the DIS fuse had blown, so i replaced it. The fuse would repeatedly blow when started until i unhooked the front coil pack and ran it. When that worked I reconnected the front and disconnected the back, and it ran without blowing the fuse. So i hooked both of them back up and and oddly enough havent blown the fuse since. When i ran it after that i was getting a code for a cylinder 6 misfire. When I took the rear coil pack off while i was replacing the plugs and boots, i noticed the gasket was worn off and there was some condensation on it. I looked down into where the plugs were with mirror and realized cylinder 6 spark plug was completely underwater. I removed all of the water, replaced the plugs, and ran it again. Cylinder 6 still had a misfire. at this point i concluded that the coil was burned out from the increased resistance from the water, so to test it i swapped the front and rear coil packs with each other. Just as i had figured, i now have a miss on clyinder 1. i went ahead and bought a new coil pack as well as a new control module, when i put it on and started it, cylinder 1 still has a miss. I figured i could have burnt out a plug so i swapped plugs with cylinder 3 just to test it and cylinder 1 is still missing. If the miss followed the old coil pack when i moved it to the front, then why is it that i have the same problem with a new one. If i had a problem with the wiring, then why isnt cylinder 6 still the issue? Hopefully someone on here has a solution.
