Check the voltage at the input side of the coil. There could be a bad wire in the ignition wiring. For example At times I have 6 volts at the battery and only 4.2 volts at the coil. It should be 6 volts also. I found a corroded connection in the ignition system. If my truck is having problems starting at times when the battery is low. I will run a temporary wire straight from the battery to the input side of the coil (i use alligator clips to hold it in place). It is only there when I am cranking it. Once started I take it off as the engine will not turn off with the wire in place.
