Hey. thanks for the reply. i thought it may be the module so i replaced it with one sourced locally with no luck. if i pull the C wire off and crank it is showing a 10Hz signal, but will still not ground the coil. if i take a jumper wire from battery negative and tap the coil neg i will get spark. coil neg wire to ignition module is good, ignition moudle has good ground. ran a jumper from battery neg to ignition moudle to be safe. iginition module is getting 12.3v with key on. messed with the air gap anywhere from.001-.040 to see if that would change anything.
