/forums/images/graemlins/confused.gifI am a newbie to this site and am hoping that someone out there is kind enough to help me out. I've recently purchased an '83 K5 with the 6.2 diesel and my problem is this...I recently replaced the mechanical fuel pump and have been trying to crank over the engine. Last week I tried starting it up, but the starter kept on cranking after we pulled the key out. We ended up having to disconnect the batteries in order to get it to stop since the ground for the battery started to melt! There was also smoke coming from the starter/solenoid area. I thought the solenoid was fried, but we removed the starter and put some jumpers on it to see if it was the solenoid, but it worked fine. Since then, I re-assembled that stuff and tried to crank it over again, but the same thing happened again, minus the burning of the wires, but there was the same smoke coming off the starter area. I'm thinking it is a problem in the steering column. Please help...the engine used to start up the first time and I haven't even driven this thing yet(due to other things). On a second note, when I used to be able to start the engine(before I replaced the fuel pump), I couldn't get the tranny to shift out of first gear(TH350). I'm thinking it is a vacuum problem, but I don't know.
