Ran out of gas and now it wonr run.

I was driving doing my road and the engine just stopped, ran out of gas. My gas gage doesnt work so I didnt know. No big deal right? Well I have my dad get me some gas and we try it out, it wouldnt run. So we poured some straight into the carb and it would run for a bit until it burned up that gas. Then after awhile it would run BARELY with the choke all the way open and me pumping the gas over and over.

I took the filter out and blew into it, it wasnt clogged and there was gas past it and before it in the rubber lines so I guess that mean the pump is working.

Also when I dad poured some gas in, gas came out toward the linkage like there was a leak. I tried pumping the throttle over and over to get the carb primed but i never really smelled gas or saw any.


There is a small "roll pin" like object thats attached to a linkage and moves up and down and has a small cotte pin type deal at the linkag to hold it on, When you press the pedal the linkage lifts it up higher. When I would prie this (lifting it up and down) it seemed to be getting gas into the carb and it would run a little bit.

SO, Is my carb out or what? Can a carb just die on you randomly??

Same exact thing happened to me when I first got my truck. Tried putting gas in it and nothing. It is most likely your fuel pump.

So a fuel pump can just randomly go out? Ive been driving the truck everyday and let it sit for a day (yesturday) Started her up, ran fine drove it ran out of gas and now this. Otherwise I never had any issues

the added wear of running it dry could have done it in

I drove mine daily for over 1500 miles by the time it went out suddenly.

My truck sputtered and died like I had run out of gas but my fuel gauge said I was just getting close to E. You may have more gas in your tank than you think.

Also a chunk of rust could have gone in the fuel line and clogged the pump. I think if you change the pump you should disconnect the fuel like from the tank and blow it out with some compressed air. Take the sender out of the tank and make sure the filter didn't fall off either.

Do you have a V6 in your GMC? I had the same problem with mine. My fuel pump is the type you can disassemble. When I took it apart, I found some rust in the one way valves in the pump. I blew it out with some compressed air. After reassembly, it worked fine again.

Easy way to check a fuel pump is to disconnect the fuel line at the carb. Stick the line in a clean & dry pop bottle. Have someone crank the engine and see if it pumps fuel. If not, check the lines for stoppages and rebuild or replace the pump if needed.
