This set-up is HEI, with the coil intergrated into the distro assembly. There is only one wire to the starter (other than the large battery POSITIVE connection).

This is an ongoing, sporadic problem of mine.

On one day the car will crank up immediately and drive all day with numerous stops. The next morning the car will decide to turn over strongly but not "ignite". Plenty of fuel and starter power (and movement), but no start. Then a few days later, after messing around with all related wires and components, the car suddenly decides to start strong again and run all day.

Driving me nuts, because I never know when (or more importantly WHERE) she will decide not to start.
