Mysterious Jeep CPS failure

Friday afternoon, I got a call form Scott saying his new stroker motor had died just east of Nashville, Tn. He was going 70mph and it just cut off.

I worked him through trouble shooting the system on the phone.

When I told him to check the connector on the CPS, he told me that he had found the trouble. The wires were gone!

I did not comprehend what he was saying at the time. I thought he said they were broken. He meant GONE!

While I loaded my XJ on the trailer and hooked up the Suburban, he was laying on the cold ground on the side of the interstate removing and rewiring his CPS.

By the time I got there (3 hours later) he had new wires run from the CPS to the ECU and had it running. One bolt was inside the Transmission however.

So we swapped XJ's and he headed on to Alabama to see his girl and I took his XJ back home to swap in a new CPS and repair the harness.

It looked like some gremlin had jumped in there and yanked the wires out. I can't figure out how it happened as that wire is pretty protected. I made sure the new one is tied up out of the way of anything.

I did enjoy taking his XJ back to him Sunday. His stoker motor has way more torque than my daily driver. I managed to take some tread off the rear tires when crossing the street to where we were meeting when I got into the gas just a little bit too much.
