My GMC Sierra ran out of gas and now I can't get it to stay running.


Fuel injectors require a high pressure fuel pump which is located in the gas tank. The gas serves as the lubricant for the pump, so wen you ran out and emptied the tank completely you no longer had lubricant and the pump burn out. It won't pump gas now because it's the fuel pump is burned out and needs replacing. It runs when you put fuel in the injectors as that bypasses the pump. Replace the pump and the never let the tank get below 1/8th full (half a 1/4 of a tank).Not lie the old low pressure fuel pumps on the side of the engine blocks. Not cheap to buy a fuel pump and have to drop the tank to replace the burned out one. $$$ in costs even it you do it yourself.

Why fuel gauge not working gas guage on 2009 santa fe stays on empty even with a full tank of gas. Guage fluctuates from empty to 3/4 full to empty to 1/3 full at any given time.


It could be the sending unit in the tank or the gauge on the dash. A mechanic would test the signal coming from the sending unit to verify.

Warning light for low fuel stays on


The sensor is part of the fuel pump module inside the gas tank.
The signal is sent to the body computer, so it could be a faulty module or a problem with the body computer.
The circuit would need to be checked with a meter.

Gas light on


You don't give the make model and year so I will give a generic statement.
The low fuel sensor is in the gas tank and its a part of the sending unit for the gauge. There could be a problem with that sensor, or a short in the wiring back to the gauge on the dash. Someone would need to check that circuit at the tank.

My 1996 chevy truck want stay runing,when i push the excelerator it die i change the fuel relay,i reset the distribution timing. please help


You may have the same problem my Wifes car has right now- ice in the fuel line.

Dump a can of DryGas (or "Heet") in the tank, and after about an hour, start your truck. Let it run for 15 minutes or so (restart if it stalls) - if it will not run that long try moving your truck into a warm garage, let it sit for about an hour, and try again.

The DryGas does not perform miracles, and takes time, especially in the bitter cold as of late.

Fuel line icing is usually caused by allowing your vehicle to run nearly empty, and then refueling in cold weather. This causes condensation in the gas tank, which freezes in the gas lines.

I have repeated this mantra to my Wife for nearly our entire 27 years of marraige, but she still will run her tank nearly dry before getting gas, even though it has so far cost us two replacement gas tanks, more than a couple gas tank leak patches (the other problem with running low all the time is rotting out your tank!), and uncounted winter car starting problems. Please help me break the trend!

The low fuel light stays on even when tank is


Hi: Your Fuel Level Sending Unit That Is Located in Your Fuel Tank Is Probally Bad. BUT before you go to taking the Sending Unit out Of your Tank Check to see if ALL Connections To And From Tank to Gauge are Conected Good. Also You could have a Fuse that Goes to the Sending Unit,in Your Fuse Block.Check And See if You Have A Fuse Labeled Fuel Sending Unit or Fuel Sensor. If you end up Replacing The Fuel Tank Sending Unit Run Your Gas Tank Down To Almost Out Of Gas Before You Start to Remove The Metal Straps Holding Your Tank Up. Cause The Sending Unit Is on Top of Your Tank ,And Your Fuel Pump Is In The Gas Tank As Well. Hope This Has Helped You Please Send Me a Vote on How my Solutions Have Helped You And Also You Can Send Me A Testamony Thank You From the WYOCWBOY

You don;t say whether the fuel gauge is reading accurately, or whether it's always on empty. If the gauge is always showing empty, it's most likely a problem with the sending unit in the fuel tank. Check the resistance across the two terminals of the sending unit.

On a C900, the fuel sender level unit is separate from the fuel pump and located on the right side top of the tank, accessible by removing the trunk floor lift up panel (the pump is located on the left side top of the tank.
Possible problems are: electrical line off or broken, float not working (it's fairly delicate); or gauge not working.

Test the resistance of the sending unit with the lines disconnected, the resistance should be 2.6 to 3.8 ohms full tank, 63.3 to 67.5 ohms empty tank; and test for voltage across the top of the sender unit, if no voltage, that's likely the problem!

If the gauge is otherwise reading accurately (showing 'full' for a full tank, etc) then the problem is likely a gauge malfunction and can be simply replaced.

Good luck!
