so Ive run into a weird no spark issue on my 73 383 charger that I originally thought was a bad coil. I cut apart the entire engine wiring harness because the car was originally a 318 that I swapped the bb into, so I could see if I messed up the wiring somewhere along the line. after fixing a few things and re taping the harness I am still having no spark at the coil, but am now getting power to the coil...ok. replaced the coil with a brand new msd, still nothing now it seems like I'm getting a crap ground to the coil from the ECU. switched to another unit I had laying around, same thing. Now it looks like I'm getting ground from one of the prongs on the ecu that is NOT supposed to supply ground. I'm at a total loss... if anyone can chime in that would be great. Also switched in a new ballast resistor. also not getting any crank from the key , been bypassing and cranking just from the starter solenoid.. not sure if this has anything to do with it or not..
