Goofy ECU problem

Ok, ive had problems with my car getting spark. Finally got that cured and I had the computer just laying on the floor from some of the related tests... So, I mounted the computer back down on the floor, and... NO SPARK to the plugs again. The computer CANT be grounded to the body of the car. If it is, there is no spark. I unplugged all 3 wire harnesses from the ecu and plugged each of them in there by themself. With each plug plugged in, if you ground the ECU, you get a slight spark where im grounding it out at. So, it has the problem with ANY of the 3 plugs plugged in. I dont get it. I unhooked the AFM (that was the cause of my no engine spark) and the computer still had this problem. The engine seems to run fine, as long as the ECU isnt touching metal... Any ideas? I would like to get my carpet laid back down. Thanks

**oh yeah, Ive tried both ECU's i have.. and they both have the same problem.**
