the 351m isnt wanting to start. It ran untill a few days ago, I was moving the truck and it just died on me and wouldnt start back up. After a little searching I found there wasnt any spark getting to the distributor. Put a new coil on, still nothing. Found out the cap was broke so I put a new cap on. I went to crank it again and it started to turn over, then didnt. Any ideas?
