Hello everyone,
I'm gonna feel stupid as I've been on many boards and even moderate a few and this is where I find my experience with wrenches lacking.
I picked up a 1991 V1500 Burb with a dead 6.2L recently. Rebuilt the motor as one of the connecting rod caps failed and led to crankshaft failure as well as a few other problems. Put the rebuilt motor in and runs like a champ, except that the speedometer doesn't work. I have also noticed the tranny doesn't want to shift into overdrive, but I think the kickdown linkage is out of whack as well, I will adjust that tomorrow. My first thought was the VSS on the T-case. I have a buddy with a 90 K-5 with the same sensor, so I swapped it, nothing changed. I would test my old one, but his K-5 is currently out of commission.
I pulled the cluster and found a really bad splice that went to one of the wires on the speedo, so I repaired it. Now instead of rising just above the lower side peg on the speedo, it rests on the peg. Did I make it worse? Right now, I'm leaning toward two different possibilities, first, the computer that rests by the brake booster. I believe the wiring goes to there (correct me if I'm wrong) and don't know if that is really functioning or not. My buddy offered his K-5's to try, but it's a 5.7L and even though they look similar, I wasn't sure if they were compatible. My second thought on this is I have a short, but not sure where as of the moment. I could start shooting wires, but that's something I don't want to do unless I have to. I did just realize I could potentially borrow his cluster to try it out as well, maybe I should try that.
Anyone have any ideas or suggestions to try? This is a really nice very loaded 1991 that runs great thanks to a fresh 6.2 and a tuned up injection pump. I cannot wait to actually take it out once this is fixed.
