No spark Mopar dizzy and FBO box & coil

ECU is well grounded, in fact I never messed with while trouble shooting it. It is bolted to the inner fender on top of 1 inch spacers so air can get under the ECU. Think I will take it off and clean up the bare metal just in case. I let it run and wiggled wires trying to get it to quit but no luck. And I agree about the ECU, maybe it's on its way out, I will pick up a cheap parts store ECU in case it does it again. I still have to unwrap the wires and make sure they are all ok also. Thanks for all your help, I am glad it fired up but would like to know why it had no spark to begin with.
