I have not checked any fuses or wiring yet... I just got the truck shipped from VA to here in Florida. I put a set of tires on it, a battery and changed the oil. It's off to the trans shop for a rebuild and a new torque converter monday. It has a really big power steering fluid leak up front near the center of the radiator. I am just shocked that someone (the previous owner) would let a kick ass truck like this get to the condition its in now...
Matt, I too used to be a tech at a Chevrolet dealer in the late 80's and early 90's. Your over the phone check engine light diagnosis story is awesome!
