The truck was running fine i pulled it out of the drive and parked it and came back 2 hours later to pull it back in the drive and it wouldn't crank. Before we replaced anything we were getting a white spake. We tested and determined that it was the ignition coil that was bad we thought. While finding TDC manually the old rotor we noticed would not turn at times and after replacing the distributor and turning the motor over we discovered that the new rotor wasn't rotating at all. The engine didn't crank or run do you think that damage was done to the valves.
Thanks, XXXXX XXXXX to confirm what i thought it was. hopefully the damage is min. if any..you've been a great help. wish i would have found this site before i start working on the truck this morning.
