As far as I am concerned this is an exact diagnosis considering the chain of command in no spark. My brother checked and there was no spark coming into the cap, but spark was coming out - which means you have to trace the fault backwards from the cap. Coil sends spark to cap which we had checked and was fine. CPS sends spark to coil (brother didn't have time to check). Mechanic jiggled wires that lead from CPS to coil and car would short out. Can't get a better diagnosis than that. I believe they choose their words carefully to cover themselves just in case it starts acting up again. My brother also jiggled the wires in that vicinity and felt it was the CPS as well or the ECU. If you note most of the folks on these threads about this intermittent stopping thing have taken their vehicles as well to very reliable and competent mechanics and have had a hit or miss in getting it fixed. Intermittent problems are very hard to solve even when you get the car to stop and stall since you have to do it so many times to track down the culprit. I'm confident that they have solved the problem. CPS is Crankshaft Position Sensor.
