My mistake on the double post - Eric and I posted at the same time.

FYI, these computers are pretty durable - they usually are not the cause of an EFI problem. It's pretty much the last alternative option.

I'm sure you can source one from a junkyard for cheap - these trucks are everywhere.

You are kind of restricted since it's a 96...so find a truck that's just like yours and swipe its computer.
