No Spark. Is it the ignition-module (Mallory dist.), the ballast box/rev limiter (Summit) or the coil (Eccel)?

**EDIT** Mitch, I'm gonna answer this just cause its so dumb. He got a flat bed wrecker/tow rig to come pick him up the 1st time the car broke down on him. In other more simple works he called a tow truck to come get him. The tow truck that came was a flat bed type like a roll back or ramp back and not an old beam style tow truck. WOW some people on here

**EDIT OFF*

Mallory dizzys are known to have probs with zapping the ignition module with the slightest amp of voltage spike or loose grounds. I was at the track on a T&T night and my friends chevelle had a prob like yours. His ground wire from battery to engine block loosened up just enough to not make connection and that killed his Mallory ignition module

So if you had a hot lead off battery come loose, you know they always spark when coming loose, that could have been enough to zap the module.

The coil is another place to look too. I never had much luck with accel coils. Most I have tested has been weak out of the box and didnt hold upwell to high vibes like in a car with big cam that shakes the whole car, or in a car that launches hard, or in high heat.

So my money is on one of those two

Dude..... You have a flatbed El Camino? What part of Arkansas do you live in?

As for your question, it does sound like there's too much voltage getting to the coils and it's frying it out.

that, or, when the battery got knocked around, it pulled on whatever wire you're talking about and broke it on the inside. test all of the wires again.... it's a continual process on old cars...

meanwhile figure out of spark is getting TO the coil....

Honestly beyond that i don't know...

Hey.. for the record, do you have an american flag mural on your back glass?

don't get me wrong man... El Camino's are cool as hell... i'm just.... still freaking out about the "flatbed" thing.... and honestly i'm surprised no one else caught that

in case you purely had an entire song up under one thousand miles in the past, deliver it to the placement that carried out the song up. it extremely is obtainable they'd have used incorrect spark plugs and wires. yet no, there is not any thank you to apply a meter to learn your IPM or CPS. you are able to attempt person sensors in spite of the fact that it extremely is a royal soreness interior the you comprehend what. My wager is which you particularly prefer a sparkling coil %. for the three cylinders that are no longer firing or a crank sensor.

shorting out coils, too much juice. Had twin marine 454 omc boat motors that happened alot to the starboard side engine, could never figure it out. take the coil off the other motor, work just fine for about 3 weeks, than burn up, but only on the starboard side, both engines were identical in every way.
