Few months ago my truck cut out driving down the road, found out it was my fuel pump. Ordered a new pump and installed and everything was good. About 3k miles later, my truck would not start periodically and then wouldnt start at all. I assumed it was the pump but foud it to be a weak/bad coil. Replaced coil and solved the problem. Now about 3 months later, my truck cut out and start slowing down,backfired once and went away. Then today, cut out and died. Pulled over and it started right away. Threw code po351 which is coil circuit code. So is my coil defective already? Msybe pcm? Any other thoughts? Would the coil cause the backfire, maybe by gas building up with no spark for a second and igniting at once? Thanks
Wires look good, no worn spots. Truck did it again today. Driving 55 and truck starts cutting out, then truck backfired and cleared up. No code this time. I replaced the coil under warranty for the heck of it to eliminate the coil. Any other ideas if it does it again?
