The gauge is driven by the selector valve. Have you checked fuses?

 

Yes all good

 

Can you hear the valve do anything when you throw the switch?

 

Only in dash

 

You have to unbolt the valve from the frame, and I recommend taking off the fuel lines (plug them with something so they don't leak). Then, with the valve in your hand, unplug the wire loom from it. Go to your dash, and hit the button to switch tanks. Go back and plug in the selector valve, and you should hear a quick "click" sound of the valve moving. If you don't hear it, then your valve is stuck on one tank.

Not to sound like an ***, but I already told you to go put 5 gallons of fuel in the tank you were running off of earlier when it died, and see what happens. If your truck fires up and runs, you have your problem right there. Asking questions without doing that first is just wasting everyone's time, because it would tell you without having to check out the valve like I just said up there^^^^ that you have a bad selector valve and a bad showerhead at the same time.

 

Sorry I tried putting fuel in it and tank would only take around 2.5 gal I will have to check fill pipe to make sure no blockage if there is a blockage it may be that the vent holes can't work and the tank can't breathe just discovered that this morning I will try all else and let you know what I came up with thanks for the help

 

Or you could be filling up the tank that's full and the fuel pump isn't pulling from. What about putting the fuel into the other tank? With my truck, even on it's worst day, will never overflow from a lack of a vent with a 5 gallon jerrycan. The jerrycans just don't flow fast enough for the tank vent to be an issue.

Your other option would be to take off the rubber hose on the fuel pump and run a much longer one to a 5 gallon can on the ground and see if the truck runs then. That would also point towards a bad selector valve.

 

if the tank that is supposed to be almost empty only took 2.5 gallons, my guess is a bad selector valve drawing off one tank, but returning to the other tank.

 

Thanks guys

 

I doubt that's the case if he was able to make almost 300 miles on the tank he was using. In any case, it all depends on what he ends up finding.

 

Not sure yet but changing the mechanical fuel pump tomorrow I'm pretty sure that's it. Sounds like you may have same problem. $77 OEM. I also had loose injector lines that I tightened,not the problem. Not leaking anymore but still stalling

 

4 gallons added same issue could it be the injector pump cause once running even if I have accelerator to the floor it still dies

 

How hard is it to start, and does it restart immediately after dying?

 

Very hard to start and doesn't start back immediately

 

It was running off empty tank fuel selector valve out but she is running thanks guys
