Well this is wired, put in a pro bilit distributor MSD 85551 with a accel 300+ ignition worked great came back a few days later it wont start. check the coil,good spark, but no spark at plugs maybe every 4th or 5th turn of the engine you might get a weak spark. would the cap or rotor be bad they look great no crakes or anything.
what to do? or just replace the cap???????

Test the resistance in your wires first. I'm not sure off the top of my head what the value is but if youu see a MAJOR diff detween several then start there. I think its like 1000 ohms per foot. what you will be looking for is a wire(s)at something way over like 10- 20 K ohms.( no comments on MSD).
