You should do that, and also check and possible add a ground to the back of the head....like i said, ground are only a few bucks, and never hurt anything.
And actually, My car started, and ran. I did donuts in a parking lot, and as i went to pull out the car died completely. Had it towed, screwed with it for 2 days, finally added some grounds(Back of the head directly to the battery) and it fired right up. But i had the same symptoms, AEM wouldnt connect properly, my pump was turning on and off while i was supposed to be priming.
