I have a 2007 JKU I was driving down the highway it started missing bad bad I turned it off and restarted it ran fine about a mile the started missing and died . There was no spark from coil pack so went and replaced it still no spark .
Had it towed back to my house stopping at parts store along the way scan said PCM was bad so I ordered it , while waiting for pcm to get here I for some reason got a test light and was checking all the plugs to be sure and found M-19 was blown I put new fuse jeep started but was missing and all of a sudden the new coil pack shorted out and jeep died .
So put old one back on and changed fuse again o and M-19 is ASD #1and #2 is what it says . Ok jeep still misfiring so put new cam and crank sensor put another new coil new pcm and new plugs jeep still runs like crap well at the coil # 3 has no fire coming out of the coil pack all the others are firing but not 3 how’s that happen please help this jeep is my only car and it’s been down for 2 weeks now .
