So I have an 86' C10 that has had a 350 installed in place of the original V6. When I got it it had starting issues so I replaced the entire distributor and everything was running great. So this weekend I ran around and picked up some tile and drove it home and parked it, the next day I went to start it and it just cranked but wouldn't fire. It was getting fuel so I assumed it was a spark issue so I looked for any loose wires and checked the distributor cap and everything looked fine so I let it sit until I could get some help. The next day I wanted to check for spark and pulled a plug wire off and told my wife to crank it and it fired right up, could I have moved a wire somewhere that was loose or grounding out causing it to not fire? What wires should I check to look for any issues?
