2000 TJ Stalls when driving

I have a 2000 TJ 4.0 straight six manual it seems to stall on me at random points so far I've tried the ECM, the Crankshaft sensor, and ignition coil pack and spark plugs. It keeps kicking the code for ignition coil. I am out of ideas need some help

Re: 2000 TJ Stalls when driving

Welcome to the garage.
Did you already measure the wiring from the PCM to the ignition coil? You need to measure for continuity, while messing with the cable loom, and see if there is no wire break. You also need to measure from each wire to ground, to see if there is a problem with a shaved wire which shorts to ground.
A known problem with the 4.0 is wire shaving at the back of the cylinder head. The cable loom passes close to a stud and can shave due to the movement of the engine while applying torque (acceleration).
