Just picked up the used computer tonight. With any luck I'll find out soon if it is the problem, if not I'm going to be tracing wires.

IT'S ALIVE!!!!

The used computer worked! The truck runs.

Thanks everybody for your help.

I had to jum in with my opinion of Autocomputerexchange (ACE)...My 99 Durango had an intermittant stall in hot weather traced to the PCM. A replacement from ACE fixed this for about 2 years. Then it failed again with the speed (cruise) control going cyclic or intermittant. Got another ACE replacement that was bad upon arrival. They honored that warrenty and sent me another bad one that would not allow the vehicle to upshift. Third try with them was the charm and this one has been good for 2 years..Just so you know, there is no assurance that they test all or any functions of these modules. They send what they have on the shelf. I also bought one for my 95 Avenger (OBD 1+) that was good. Just buyer beware and hope you get one that works...

My brothers 2000 ram pcm went out ( inj 4 driver) and i was going on a trip with it, so i pulled one from a JY and thats been bout 6 yrs ago and its still in there..no codes or lights at all i was surprised..
