P0352 JEEP - how do I fix this ? Swapped coil packs but the truck wouldn't even run! Help!

Question

My jeep keeps losing power and is rough while driving. I changed the spark plugs and swapped my buddy's coil pack (from the same jeep) and put it into mine. But when I put it in the truck wouldn't run. Please help

Answer 1

P0352 Ignition coil #2 primary circuit

You obviously have no power to the coil pack, see if fuse number 18 is open and that the fuel pump turns on, This will be a good indication that the ASD relay is putting out power, If this is good change out the PCM with your buddy.

The funny thing was when I put the old coil pack back in the truck ran but still like crap.

Its not hitting all 6 cylinders, your code says it all you either have a connection problem on coil number 2 driver or the PCM
