Hi Guys! It was the timing chain. Original aluminum timing gear was almost smooth with all the teeth almost gone. THANKS ANYWAY,
and YES, I will probably not waste my time posting here again.....
75 Coronet 400/4bbl, just quit running while ideling in driveway. Will not restart. Sounds different then before. Where should I start? Fuel sys? or Ele sys? and what about that ballast resistor?
