No, I can hold the screw driver and see the cranking spark. It 100% is possible because I have done it many times.Not possible
Even if that second person JUMPS when they get electrocuted you are still missing if it was just key on spark or cranking spark
This. That's why I said to tap the crank sensor wires as close to the PCM as you can get and see if that same AC voltage is there.Then either PCM is bad or crank sensor signal is not making it to PCM
I was jokingNo, I can hold the screw driver and see the cranking spark. It 100% is possible because I have done it many times.
If I can hold the screw driver, and observe a spark to the head or block or intake, really any major metal part of the engine, while it is spinning over, that is an effective test of cranking spark. And I have done it many multiple times in my years of owning 2.9s. I can even assess the health of the coil and TFI on a 2.9 by the color and quality of the spark.
True, it won't show timing, but it wouldn't show timing on a single cylinder engine either. A timing light would show both spark and timing, but not quality, and you need plug wires for that.I was joking
What about the timing?
50/50 test does/tests BOTH
