Just started my 75 to take it out for a spin. Was letting it warm up a few minutes and then all of a sudden the car died. It is getting enough gas and the engine turns over like a race horse but it won't start. I am thinking elelctrical but not sure. Any suggestions for me as to where to start to trouble shoot this?

 

Thanks

My first check would be ignition module.   Mike

That would be my first guess, also. Check for a spark at the plugs with an old sparkle plug.(Or just grab a wire while someone else cranks it over ) GM HEI distributors are notorious for burning through the rotor, and cap. Look on the bottom of the rotor and see if it looks like there has been a rusty lightning storm. If so, replace the cap & rotor, reguardless of if that's the actual problem. Anything that makes it hard for the spark to get to the plugs is murder on the ign. module. If there's no spark @ plugs, it could be the module, the 'pole-piece', the coil, or it could be that the big red wire has come off of the dist. cap. I have seen many HEI modules go to the crapper while the car was running. Sometimes, they'll start again when they cool off, sometimes not. Do some checking and let us know.

Thanks guys it gives me a good place to start. I will let you know how I make out

On HEI's the two small wires going to the pickup(pole piece) some times give up the ship after being worked back and forth from the action of the vaccum advance. That's where I've had a HEI or two go South.

Thanks for all the help guys. It was the ignition module. Runs like a champ now
