76 K5 with a 350. I washed the truck went to move it a coupl eday later and nothing happened when I hit the key. The gauges jump and twitch like normal and the headlights seem bright so I clean both sides of the + battery cable and the other wire connection on the starter and still nothing when I hit the key. No clicking, nothing. So I turned the key to ON and hoped under the truck with a screwdriver and arched the starter. It fired right up. I didn't have time to peel back the cable insulation and inspect for corrosion and I seriously doubt it is coroded so what other things might be the problem? The electronic deal inside the HEI? The switch itself? A fuse? What do you think? The electonic thing in the dist was replaced back in 1999 sometime. Thanks, Dan I know there is a way to check the electronic deal in the HEI with a meter but not sure how to.
