I'm still working on getting my '87 to run since doing a compression test on it. But out of curiosity, if a computer goes bad in one of these older vehicles where do you get a replacement for it? Not saying mine is bad since I haven't done enough testing but I'm curious as to how you deal with that situation.

 

You should be able to get a remanufactured unit from Orielly or Advance.

 

Other members have found the Cardone branded PCMs are not truly tested. It's a crap shoot whether the replacement will be a good one or not. Replacements from NAPA have been pretty reliable from the reading I have found on this and other Ford truck related sites over the past few years.

On another note I frequently see ads on this site when viewing questions about our computers. I'm sure there is some gizmo that targets keywords, but my point is I do see ads for replacement PCMs from time to time on this site from other vendors.

 

I've heard that the 2 safest ways to replace is to get the numbers off your actual eec unit or off the door jamb, which mine didn't have. There are a few rows of numbers and letters and then a few BIG letters like U2X1, in my case. The replacement I got today after searching for a month had the big numbers as U2X so we'll see if that's close enough tomorrow when I hook it up. Junkyard parts can be scary but also tons cheaper.
