Try this. Check the fuel inertia switch. Should be locatedi n the rear in a pane, fuel tank side and not far from the fuel tank. If you have an owners manual, it's instructions are in there.l. Pull to reset. Good luck -Ned-

SOURCE: my 1993 GMC Sierra Z71

Hi, that's possible but first check the ECM fuse and use a test light to check for power to the injectors on the red and white wires. The computer uses a number of sensor inputs to calculate the injector signals required. If these signals are not available, the computer cannot send the appropriate injection metering signal and will usually set the engine light. Is the engine light on?

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.

Need to replace gas filter have to pump gas serve l times to get it startled


Hi Friend: Your Fuel Filter is Located at your Fuel Pump Assembly,In your Fuel Tank, On your vehicle the fuel filter does not require that it be replaced like one that is outside the fuel tank.

You might check your fuel pressure regulator or injectors.

FUEL INJECTORS WON'T LET FUEL PUMP OUT


Check your fuel filter and see if fuel is getting through it. You will know whether to look forwards or backwards after looking at the filter.

If you have the switchable gas tanks check the switch. Usually one side will always work, but if it came apart inside it may block the lines.

Since you have pumps at the tanks you should be pushing fuel, not like a diesel that pulls fuel. I would say a TPS (throttle position sensor) could be bad as it tells the injectors to let the gas in, but you say the injectors are dry. When you test, block the TPS open a bit or test for fuel before the injector rail.

I removed the injector and fuel regulator assembly from the motor all in one piece, and left the electrical lines attatched in an attempt to see if the injectors were working. I attempted to start the van...


Yes, if everything is still connected properly, except that the injectors are no longer seated int he valve head, then you should see little spurts of gas coming from them when the engine turns over.

Be aware though, that it might not be your fuel injectors that are the problem. You need to finish checking the rest of the car before making that assumption.

Once you know the injectors aren't firing, you need to check the fuel filter and the fuel pump to make sure the gas is getting from the tank to the injectors.

You should have a fuel filter located on the passenger side of your car near the gas tank. Follow the gas lines under the car to find it. It is good to change it anyways, but you can check to see if gas is coming from the tank to the filter by removing the rear line

** BE CAREFUL, Gasoline is EXTREMELY irritating to the eyes and skin, and it WILL come out when you remove the line from the filter***

If it is coming from the tank to the filter you don't have to check your pump. Then replace the rear gas line, and remove the front gas line going to the engine and make sure the filter spits out gas while the engine turns over as well.

If there is no gas getting to the fuel filter, you will need to check your fuel pump, which should be located inside the gas tank. You can check it by getting under the car while you have a friend turn the key to the "on" position, but not starting the car. Do this 4 to 6 times to make sure you hear a little "Click, woosh" type sound that lets you know the pump is triggering.

If you have gas coming from the tank, through the filter and it is still not coming through the injectors, then you will need to rebuild your fuel injectors.

This is not hard to do, and consists mostly of changing the little gaskets in the injectors. But be aware that there are lots of small parts and the job cannot be rushed. Also be aware that lumina fuel injection systems are very sensitive. Make sure to disconnect your battery cables before removing the injectors from the system.

Help w 1994 chevrolet truck


This injector set-up needs a specific fuel pressure supplied to the fuel rail to even start, much less run properly. The fuel pump is immersed in fuel inside the gas tank to keep it cool and not burn up. Running the fuel level low causes more heat in the pump and interuptions in proper fuel pressure. AC/Delco pumps have proven to be a reliable fix, the aftermarket pumps only last for a month or two sometimes. Check fuel pressure under the hood and power and ground to fuel pump at electrical harness at top of gas tank. This truck needs a fuel pump.
