Relays aren't usually thermally sensitive. Is the check engine light on? If so, rent a scanner, read out any code(s), and pursue to repairs. How hot does the engine get? Does it quit when it gets hot, or does it not start after shut-off? The fuel pump should run for a short time, then stop when the key is first turned on (engine off). If it continues to run, the pump is near it's demise--replace it. Replace the fuel filter if it hasn't been changed recently. Hope this helps.

1993 Buick regal custom run fine until I turn ignition off then I have to wait about two hours to start it again because the file pump wont kick on wat could be wrong


This may be related to the antitheft system The system is known for turning off the starter and/or injectors when it fails. Is there a light on the dash that says SECURITY or a picture of a car with a lock through it? This is a common problem worth looking into. http://www.diy-gm-security.com/

Fuel filter change did not take care of the problem car still shuts down after 20 minutes of running will not start again for about 20 minutes anyone know what the next move maybe


Have a pressure check run on your fuel pump. Sounds like fuel pump is ready to totally fail. Just had this happen on my ford expedition. And that was painful changing out fuel pump. Took 4 hours and was a dirty job too

Have a ford f350 with 460 starts runs fine till it warms up then fuel pump shuts down leave to cool down and fuel pump will work again and start again


What year? Newer models use a fuel pump module located in the rear. Some are on the rear frame rail and some are near the spare tire. These modules can corrode and cause issues

Where is the crank position sensor on a 98 chevy malibu 2.4L? Also what is more apt to be bad, the crank position sensor or the camshaft position sensor?


If it is either sensor you will get a check engine light. So check this, A faulty fuel pump relay can cause the car to come to a complete stop while driving, its like running out of gas. It may be getting hot and shutting fuel pump down. Try swapping another relay of the same size, For the pump to see if its a bad relay. It may be is shutting the fuel pump down, when it gets hot.

There are too many sensors to be able to narrow it down it could be the fuel pump relay under the hood, I would start there.

Bought this car in January, everything was fine. now that the weather is hot, seems the fuel overheats and the car dies. Left to cool down, will run till it gets hot again.


Only way to really know is to test thing but the things that can do this are the fuel pump or relay. The crank sensor, the ignion module, the coil.

This is providing the coolant is not overheating. If the coolant is overheating then as the motor gets hotter,,less fuel will be added creating a possible stall. When an engine is shut off they usually get a little hotter by the sensors before they start to cool down.

2000 vw cabrio runs normal and shuts down, takes 5 to 20 minutes to restart, engine cranks but doesnt start, changed ignition coil, pulled diagnostic codes getting short to ground codes on cylinder...


On some models, the Engine Control unit has a power supply relay. These relays some times get internal dry solder points. After driving for some time the the solder will get hot and separate. When it cools down it makes contact again. You will have to replace this relay or open it up and re- solder the solder joints. The relay is usually located on the main relay station in position 3. the relay station is located behind the right dash panel.[right hand drive vehicles]. You may need to refer to a manual for your specific model to find the exact location of the relay.

Engine dies when running. Intermittently dies while running no sputtering or other warning, all of a sudden the engine is off. Mostly happens at lower rpm's. Starts right back up after putting it in park.


first thing to replace and cheapest would be the fuel filter ,if that doesn't fix the problem , it may be the fuel pump . GM fuel pumps are in the gas tank, and they have a built in thermo fuse . when fuel pumps get old 60000 miles or so..the motor in fuel pump starts running to hot and the thermo fuse kills the power till it cools down then it will run till it gets hot again note the cool down time keeps getting longer and longer
