This thread will be detailing my build project on my 1990 GMC Sierra SLE RCSB K1500 that I've named Cowboy. I've owned a few GMT400 trucks over the years and I've **always** wanted a RCSB truck to putt around town in. Well, I got one last year and after a new Delphi fuel pump, fuel filter, battery, AC Delco 02 sensor, a new ICM, and some junkyard tires it now runs. It has a stumble and misfire when cold (I'm assuming coolant temperature sensor) but it comes out of it after a minute or so. Otherwise, it runs, drives, shifts, and stops pretty decently. I've started amassing parts for it and I'm about ready to start fixing it up.
First, some pictures of how it looked when I got it.
