I checked the for codes and nothing came up. Then it started!! Any ideas?????????

 

I think it has something to do with the starting system, clean/replace your battery terminals, check the wires for corrosion, the sidepost batteries are notorious for internal cable corrosion.. Check the starter solenoid for good connections.

Next time it doesn't start, have a frind play with the battery cable, if it fires up, there's your culprit.
