I figured out some wiring problems with my transmission in my truck. Changed the programing on the transmission too.
I tried starting my truck for the first time in 3 1/2 years and got nothing. Starter wire was loose, so I tighten it up. I got one click and loss power. I figured it'* the power cable going to the starter shorted out. Took the cable off and taped it off since that cable melted on the exhaust years ago.
I got the truck running and it was screeching (not good IMO). Sounded like power steering pump or the belts. It needed some power steering fluid. I started up again and the truck backfires every couple seconds. Downside, I didn't get to break in the cam. I'm hoping is ok still.
Also ran my Bonneville for awhile and still need to try and bleed the air out of the fuel lines.
