Car was intermittently not starting and was hesitating on the highway. Changed cap and rotor, plugs and wires. Repaired o-ring. Everything was great until I was driving along, accelerating, and the car hesitated then died. There was no spark. Checked components as the Haynes manual suggested, and everything seems ok. The coil tests okay, but there is a crack in the poly just above the high tension terminal. It seems as though the spark has arced across and back into the coil. Ever heard of this? New coil should be here tomorrow morning and will install.
I'm a little worried that the igniters or ECM could have become damaged. Any thoughts? Will let you know how it turns out.
