I have a 85 Blazer K5. I purchased a new clutch for it and installed it. I had an issue when I dropped the tranny. The wire on top of the tranny (think it has something to do with throttle) broke loose. I hooked it up with new wire and connectors and when I put everything back together the engine turned over once and shut off. Now, I have no dash lights (i.e. brake light, or oil light) and no noise at all when the key is turned to start. Not sure if this is the starter or what. Any advice would be helpful.

 

With electrical issues start at the beginning and work backwards.

Were there any wires that could have been pinched during the install?

Do you have a multimeter for checking for voltage at different points? Start with the battery, then check for voltage at the main link on the firewall to the left of the brake booster.
