Hey guys. Just got done rebuilding the top end after a timing chain guide was dislodged and bent all of my valves. Engine would turn before I put the heads on. Everything was fine. Rebuilt the top end. Everything turns over by hand. Hook everything up and it wont even attmpt to crank. Starter doesn't even click. I don't think it's a ground because I only undid one ground, and now it's connected again. Although when the car broke down on the highway and I had to pull over. It wouldn't crank or click or do anything after I pulled over either. Do you think there was a safety mechanism that tripped when all of this happened? Any thoughts?
