Thread: Not really a hotrod. but still a classic to me.

From your description of the symptoms.. I would've said it's ignition, but you say you have no fuel... how were you checking for fuel... also, can you verify the gas cap is the right one (vented or un-vented) ?? Since the pump is relatively new ( and carters have a good reputation ) I would gravitate elsewhere but, if you can open the fuel line after the pump and use some hose to go to a can or bottle, you should be able to run the motor for a minute and verify the pump is pushing fuel. And try it with the cap on and off..

Intermittant problems are always the worst!

Check for fuel by removing air cleaner and hitting the throttle and no fuel squirting from the jets, not even a trickle. And cap is correct. And when I removed the cap thinking it was a vaccum effect in the tank there was no whooshing sound so the tank is venting correctly. And the Pertronix is testing correctly and have spark at plugs when this is occuring. Changed out ignition due to the old prestolite icm was failing once it got hot and this is different on the stalling than that was. No back fireing when its trying to keep running as when the spark was failing. Just seems to be cutting out the fuel when vaccum raises from the idle speed. Can drive at slow speeds as long as I dont push on the accelerator to gain speed. Vaccum lines have also been replaced and routed.
Oh another thing. This is a Quadrajet carb if that helps any.
