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.

I changed the fuel pump,im getting gas to the fuel rail but none to the injectors


If gas is getting to the fuel rail, it is getting to injectors. If fuel pressure is good, probably the injector circuit is not working. With a test light you can check the injector circuit. Post back for further help. What year and make is the car?

I ran out of gas in my 99 chevy tahoe. will not start after gas was pumped. changed fuel filter and additional ignition parts & sensors. More likely the fuel pump or fuel injectors?


If you add a few tablespoons of gas directly to the throttle body after removing the air filter, or use starting fluid (ether), then if the car starts and runs after cranking, then it is a bad fuel pump.

Check the fuel pressure of the fuel pump rail to verify if gas is coming through the system.

If not, it's definitely a fuel pump.

If it were an injector, then it would still try to start on some cylinders assuming it's getting spark.

The fact that the problem started after gas was pumped, points to a fuel pump, as well.

So, I would go for the fuel pump if the fuel pressure is 0 psi or near that, or if one discovers that there isn't any gas coming through the piping when cranking.

Also, check fuses for the fuel pump and 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.

Cannot get 1987 chevy van 20 to keep running... stalls out


Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

If you had a strong stream of gas shooting out then you may have an fuel injector problem. Possibly a clogged injector or bad injector.If the stream of gas was weak replace fuel filter first and test again.If problem persists check pump fuse then replace pump. sorry for miss reading your post.

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.
