If you see no spark from one coild tower to the other, replace your cps. This sensor (crankshaft position sensor) controls the ignition module
I had the same problem. My solution was the coil was arcing (more with high humidity) and had to be replaced. Take the cowl off to view your engine look for arcing on the coil. Its a tough DIY job as you have to disconnect throttle linkage. Take it to a shop $150 bucks is what it cost me. Astroman
Some voltage must be present but the current causes the arcing.
A shorted coil or shorted coils in the rotor will cause arcing at the commutator. It should also be noted that if the brushes are damaged badly enough where they make contact with the commutator, this can cause arcing. Oh, and let's not forget that a stuck brush or brush spring will prevent a brush from making proper contact with the commutator. Arcing can result from that, too.
Arcing is electrical current jumping across a gap, or creating an arc, as in a spark plug firing, or lightning arcing across the sky.

high voltage breaking capacity
You have a wire that is loose and arcing.
Arcing is caused by a poor electrical connection. The breaker is not making good contact with the buss bar. Try replacing the breaker.
There could be two reasons. One is that the receptical is old and well used and the connected load is close to 1500 watts. Second is that the wires have become loose on the terminal screws and are arcing. In either case get the receptical replaced right away.
Always push start your car.
An arcover is the unwanted arcing of electricity from one component to another.
It's common to put arcing horns on the HV side of a power transformer to short out voltage spikes arriving from lightning strikes along the line.
