Lo-Key:

The questions about spark quality were the first steps; now that you know that the spark is very weak, the next question is why. pmc has started you down that path; point cleanliness, correct gap, and condenser quality are some of the factors. Also, what is the voltage at the hot side of the coil, both with key on, and when cranking? This is a step-by-step process; there will probably be a few iterations.
