Help when i drive vehicle starved and cut off

The baffels in gas tank r broke makein fuel go to one side and starving pump

Sounds like a vacuum leak of some kind. Depending on the Yr/ make & model it could stretch from mass air flow sensor, Oxygen sensor, fuel pump to carburetor. The car is starving for fuel or air? Could be as simple as an air filter clogged or not seated properly. Good luck

If you can keep it running with the choke set, your engine is starving for fuel, your fuel filter, or carb is clogged. disconnect the fuel line to the carb and check for flow. Fuel cut would do just that, cut ALL fuel so choking would not matter.

Check the Tank vent, If it's starving or cutting out it may be creating a vacuum on the tank. Open the tank a bit and see if it still starves at higher RPM. If it runs fine, Located the vent tube and lean it out or clean the vent on the gas cap either way. If it's still starving for fuel, then look at the petcock. If it's one of the vacuum diaphragm auto types, the diaphragm is probably bad and will need to be replaced. Dump it and get a manual valve.

Meloe77, there's a high possibility you have a mechanical failure inside the engie causing the knocking sound. (Check the oil?)
The reason for shutting off is because the knock sensor can hear it, and the powertrain control module (PCM, herefore) is trying to detune the engine to eliminate the sound, (as if it were caused by bad gasoline.) The fact that there is a mechanical knocking sound, means that the sound cannot be eliminated by detuning of fuel or spark mapping, therefore it starves for fuel and/or spark causing the engine to stop running.
My recommendation: Have the vehicle TOWED to a reputable mechanic and ask him if its possible that I'm right.

Linda, Sounds as though the engine is starving for fuel.

Fuel starving,replace the fuel pump. test drive it did it solve it. If no then next step (when it cuts out as you floor it it starves for fuel). Engine off open air cleaner look into carburator grab accelerator linkage (open secondary flap the big one) prime it does it squirt fuel from all four port or just two. Probably just two circuit . the nissan uses a seconday that is electricaly controlled. its a vacuum port they have a tendancy to stay in the closed position and not allow secondary fuel. primary should be okay that the port that is open and when you pull on the throttle mechanism should see fuel spray out. either way rebuild the carb. Oh let me give you bad new todays fuel is not meant for carburator so always look for external leaks

Does it start right back up after it dies or do you have to wait. If you have to wait for a bit then it starts back up could be a fuel pump. It is very possible that if the fuel pump shuts off you lose pressure and the vehicle will just die, it won't sputter like many think. It's not like it is starving for fuel at that time, it just quits working. I know it is hard to diagnose but I have seen a Lincoln Town Car with similar issue and it was the fuel pump. That pump unfortunately is in the fuel tank. If this helps please give me thumbs up. Good luck.

idle air control problem needs cleaned or replaced
