This tells you where to find the ecm and how to remove/install it.

 

i followed that link...but autozone has no info on it in the repair guides..i had already searched them extensively....and i beleive swartllk is talking about something other than the electronic sprk control...truck has plenty of spark and is firing good i timed it myself to make sure.

 

I said PCM, but I should have called it an ECM or ECU because it does not control the transmission. The ECU should be located behind the glove box.
