Fuel Pump or Carb Problem? Help
Car has been cutting out during driving,
What are the symptoms of a bad fuel pump?
Driving down road (with gas) and all of a sudden, starts to die, sputters, etc and stops dead.. It does start again but takes a long while. Then all of a sudden, starts to go like nothing happened.
Carb is orig rodchester, rebuilt a couple of times. Fuel pump replaced about 11 years ago (15,000 miles).
All help appreciated.

If electronic ignition like pertronix, could be going bad.

I had the same problem a few years ago. I replaced everything (rebuilt carb, fuel filter, new coil, new fuel pump, et.) and it still would randomly cut out.
The culprit: a $3 engine kill switch that went bad.

Hi
when i first hade my corvette it exhibited similar symptoms, it turned out to be the condensor in the distributor. You might try this first, as someone else said try the easy (cheap) things first.

After it quits running take the breather cover off and look to see if fuel is squirting out of both nozzles as you pump the accelerator lever.
You should have two good streams of gas with each pump of the accelerator lever. If not, it could be the fuel pump.

If it's not fuel, could be a plugged cat. I don't know what year your car is, so I don't know if it has 'em, but the symptoms are a lot like what you describe.

Usually sputters when going up-hill??
Water in the tank. You can't easily see it... but it's there.... under the gas... by the pick up.
Fuel sloshes going up hill... water moves around... gets sucked up to carb... engine stalls. Heat of engine/carb evaporates water.... car starts back up.
Just a guess of course.
Plugged filler neck water drain tube, or chronically empty tank (condensation) is cause.
Took me 2 years to figure this one out... then I had to replace the rusty tank.
