Big block chevy instantly shut off on me
Hi guys,
Was coming home today from a car show, driving down the street, when the car shut off instantly and coasted to a stop. I tried to re-fire the car and it touched a couple times and then nothing so I got it flat decked home. It looks like I have no spark when I pull a spark plug lead at the distributor. The car is still on stock coil and points. Any ideas on where to start? Thanks for the input.

Thanks for the ideas. I thought maybe fuel as well, but it is still the stock mechanical pump, and it didn't stutter like it was starving. It was like a switch shut off the motor instantly.

Coil?
Running an HEI on my ZZ4, running along I94, the engine stopped. Coasted to a stop, had fuel pressure (injected motor), refused to start while turning over w/o issue. Rode home on a flatbed, called my brother, he had a similar failure that turned out to be coil. Dropped a new coil on and it fired instantlyGreg Fast

Thanks....that’s what I suspect as well. Will pull the cap tonight and make sure the rotor is still turning and there isn’t a distributor/cam/timing set issue. If all looks good, will grab a new coil for it. Should probably switch out to something like a Pertronix while it’s apart. Originally Posted by Twentyover

You may want of check the distributor drive gear also (pull the cap and bump the starter to see if the rotor moves).

So I pulled the coil, and I had upgraded it from stock several years ago to a Pertronix coil. I was told the 0.6 ohm Flamethrower 2 was the model to use with stock points. Apparently I should have been given a 1.5 ohm Flamethrower 1, and this may be the reason the coil failed.

Dropped in a new coil today, and the car fired first try. Problem solved!
