See if you have a flashing ground to the other wire going to the coil while cranking?

Thanks for your dedicated effort.I also have tried repair info on line(autozone/alldata)a couple forums/blogs and this website.I've purchased coil pack-put on & still no fire to spark plug, so I checked ICM price & shutterred when they said $250.00 new, but purchased anyway. Proceeded to look for Said ICM, have windshield wiper covers off, inner fenderwels both off, battery & powerbox out or moveable. Jacked up 1 1/2 foot off floor, both front tires off etc, etc. Then I've started under rightside interior panels, power control modular taken out and I'm headed for the headlights and front grille, next. Did I mention it's a Canadian production model?
Enjoy the evening, I'm going to!

Have you checked the crank shaft position sensor?I would check that it will cause no spark and you can check it with a multi meter to test it. The other moderator I asked couldn't find it ethier and thought it was inter grated into the pcm.

You would unplug the sensor and measure across the terminals of the sensor. I can't find the spec on it bit most sensors are usually between 800-1200 ohms.
