I am having a problem with my Supra, it lost spark. I have replaced points, condensor & coil. I have checked the coil wire resistance & it's fine. I have checked output from the new & old coils & there is none. The purple power lead to the coil has power with the ignition key on & the negetive side has power when turning over the engine. It is a simple system but it's kicking my ass right now b/c we were supposed to ride in the AM
I have pulled one of the plug wires & used a plug tester as well as a new plug grounded to the block to confirm that there is no spark.
