It started for about a minute this time and then sputtered and died. It did generate this code though. No freeze frame data at this time. Anything else I should look for?

Ok I did one other test if it helps. I took off the plugs 2 at a time at the coil pack 6 and 3 and so on and i could easily see good spark jumping across each pair.

You need to have a factory capable scan tool and do the crank relearn.

The issue I have here is I don't have one of those and the car isn't drivable. So Im not usre what to do. Didn't you say I needed to checkt he ICM? How do we rule that out? I've noticied your in Flint if that isn't a coicidence. Im in GRand Blanc if I could get it somewhere do you know of a place I can get the relearn done at?

P was 60.....he'* good
Someone brought up earlier about using a multimeter to test the system. It was also mentioned that it can be many otehr things in the circuit w/ the crank and cam sensors but I don't think I've tested any of that yet b/c Im not sure how?

I assume I don't need to do any spark testing b/c it appears I have spark or is that an incorrect assumption?

I assume I do need to test the ICM or is that not accurate b/c doens't that handle all of the signals coming back from the cam and crank sensors?

You ABSOLUTELY HAVE to do a crank relearn after replacing the sensor. MUST use scan tool.
