I am getting weak spark to the front rotor and decent spark to the back (but clearly better). The car is SCCA ITA prepped. Brand new plugs... My initial thought was the ignitors or coils but then the problem would be trailing/leading, not isolated to the same rotor. The car won't start due to this issue.

I also cleaned the leads on the rotor inside the distributor cap but it is slightly worn... could it be this, or maybe the pickup inside the dist.? What else could cause this issue???

Thanks!

 

Swap the plug wires front to rear. If it follows then its the wires for sure. If it doesn't your
looking further back in the ignition, like cap and rotor.

 

cap and rotor was cheap enough and seemed to have fixed the problem. Just gotta figure a few more things out now. Thanks!
