Shuts off while driving


The fuel pump gets power from the pump relay on startup, then from the oil pressure switch when the engine is running. You could try a jumper to the relay to bypass the pressure switch to confirm the problem. The design is to prevent a fire in a wreck.

if your car have sensor, replace oil sensor, or try to disconnect the oil sensor then start the engine, or make sure the water and oil level are ok

1991 cavalier 3.1 driving and car stops running. fuel pump & filtre ,cranksfaft sensor all replace. Like it's shut off while driving. Relay clicks on and off when key is turned on. Can the oil...


On some of these models, the oil sensor is wired to the fuel pump as a fail safe to prevent severe engine damage if oil pressure drops. Also it may be a good idea to replace your fuel pump relay. New fuel pumps require the full supplied voltage to perform, and old relays will sometimes overheat and shut off while trying to keep up, and sometimes allow you to start back up and drive after they cool (like 15-30mins later).

During the summer time it will cut off sounds like it is loosing fuel pressure will turn over, but wont start back up until at least an hour later. Drives perfect during the winter time no problems,...


What causes this is ussually the oxygen sensor. It works when the engine heats up and if its no good, it will run your engine lean or even shut it down. check them and replace them. They should be done every 2 years.

1991 Jeep Fuel Control Issue


Hey Mudkicker,

Who ever thought of putting an electric fuel pump inside a tank of gas........

Check your other gauges for accuracy. They do that when a ground is loose.

Check the wiring from the fuel tank along the longitudinal frame for frays and shorts. Plugs are secured.

Under the hood, passenger side, check the fuel pump relay. Switch it with one of the others to test it.

Bring the vehicle to an auto parts store. Ask them to break out he code reader. Check for diag codes

Comment me back

Engine cuts off


Check the relays. A worn connection could cause this.
The fuel pump relay is often the culprit.
If you try twisting the relays, gently while it's running, or while you try starting it, you may find the problem.
Hope that's it.
