Re: Engine quits running while driving

Engines need air, fuel, and a well timed spark to run. You need to trouble shoot and see which is missing.

Re: Engine quits running while driving

The fuel tank vent line might be blocked. Sometimes the vent is in the filler cap. As fuel is pumped out of the tank, air has to get in to avoid developing a vacuum. But as others have recommended, first make sure your problem isn't spark related. Does your engine quit suddenly or stumble and then die?

It pretty much quits suddenly, all I noticed was a slightly rougher idle where the revs would oscillate a bit and then shutdown a few seconds later.

Re: Engine quits running while driving

As soon as it quits, pull off the air cleaner and while looking down into the carb operate the accelerator linkage and see if you have 2 solid streams of fuel spraying. If yes, then its not fuel related.

Re: Engine quits running while driving

"Could be the ignition module is overheating"

Not likely, as module problems are mostly all caused by layer short failure issues in the ignition coil, NOT the module failing unless it is fully exposed to the heat of the sun beating down on it, and that isn't likely.

And, YET AGAIN, resistance tests of the coil are no longer reliable for any coil other than one that is dead cold, not any heat in it. Remove coil from vehicle, find good auto parts store with off vehicle electronics tester, one that runs coils, put the coil on it, let it run, get it all the way up to operating hot temperature, and let it run for a few minutes.

Re: Engine quits running while driving

Cheap, easy diagnostic of the fuel tank and lines would be to disconnect and plug the fuel line at the fuel pump. use a short piece of house to go to a small gas can on the ground. IF the issue is fuel related, this would tell you if the problem is before the fuel pump, or after the fuel pump.

Re: Engine quits running while driving

I would put a Tee on the line the goes to the carb and run a 1/4" return line back to the tank. This is almost mandatory with the new gasoline blends..

"I would put a Tee on the line the goes to the carb and run a 1/4" return line back to the tank"

So, a line back to the tank, between the fuel pump and needle valve, that would be great, reduce the fuel pressure to nil, that is really great common sense. I guess this modification has to go along with the Top Fuel/Funny Car locked out timing curve and "rip the vacuum advance off" lack of clear thought.

NOT FUNNY ONE LITTLE BIT, but, that is one of the ways some of you are going, the wrong direction.

No offense , actually a compliment as I meant funny as in makes more sense than reducing fuel flow/pressure.

Re: Engine quits running while driving

Well evidently the OP either doesnít need any help after all or he isnít too concerned about the issue as he hasnít logged in to the site for 5 weeks.
