Default No spark!!! HELP ME PLEASE!!! I just went back to work and this happened!!!

I was backing into a parking spot and she just died. I have fuel and air. I replaced the cap and rotor and ignition module and she just cranks no start. I tried jumping the plug from distributor (A and C (green and black)) now I jumped the connection coming from distributor. Should I have jumped on ESC side??? What can it be??? Pick up coil or that fusable link on wire coming from distributor??? PLEASE HELP ME I FINALLY WENT BACK TO WORK AND NOW THIS...

What have you done prior to this? The hei distributor has a pickup coil that sets underneath the distributor rotor, if the insulation is shot, it will cause no spark. You can remove it, real PITA, I think if you have an ohm meter you can pull the plug off the ignition module, and check it to ground, should be infinity. Could also be the ignition module, I'd look at the pickup coil first. Congrats on being able to return to work.

I replied, but I don't see it here so I will write again... I never joined forum so I'm learning to use OK... Anyway I replaced cap, rotor, and module. I also tried jumping the ESC (green and black (A and C)) from pigtail coming from distributor. I also checked coil with multimeter. Should I check fusable link and pickup coil... I'm glad I'm back at work, but I'm in debt up to eyeballs... What do you think I should do???

If I check both leads should it read between 150 and 900 ohms and if I check one lead and ground the other than infinity... That is my next test... I told you I'm new at this forum thing look above... My answer somehow ended up before your question lol... I hope it's this even though I'm broke.... I really despise this virus!!!!!

In a long time ago I had an 82 with ESC, truck. It had the module, and pickup coil in the distributor. After 3 trips to the parts store for a module, they tested, and as it turned out they were not testing it as should, and screwed them up. The pickup coil where it sat on the distributor mica(insulation) had deteriorated to the point it was shorting to the base/ground. I replaced the pickup coil, cured the issue. You should not read anything to ground from the pickup lead to ground other than high resisitance. Yes the %^^&^%$##virus sux.
