I will admit I have only done this on a running engine.

I know there's no problem hearing them on a running engine. It was the notion one would expect to be able to hear them above the starter or keep the screwdriver in place as the motor rocks back and forth during cranking that caused my amazement. Try a stethoscope. It works better because you get both ears. I use a cheap one from an old blood pressure cuff. I use it for a lot more than just listening to injectors click. I have a metal tube shoved in the hose as a probe.

Now your important question: What I didn't ask, is the swap plug and play? or did he have to rewire some of the connections.

I've had a hard time following the multiple posts and strange line breaks, but I gather it was an 82 Diesel getting an 83 motor with 84 electronics. I wonder about the engine harness. I had serious rot in my 84's harness that shorted the red/yellow and green/white injector wires at their splices under the kudzu so to speak.

Man, this site is just crawling slow.
