1999 TAHOE z71 STOP AFTER FUELING GAS

Fuel pump dead or dying. Injection systems need 110 psi, and a pump only doing 30psi will still not run .

Year make and model ? You may have cooked the pump or picked up some junk from the bottom of the tank, if the fuel pump is in the tank.
Running on less than 1/4 tank is tough on an in-tank pump.

I prefer bosch plugs :

file pump

Since the Uplanders have the long (front to back) skinny gas tank, with the outlet to the rear; if you run out of gas with the front/nose inclined lower than the rear, then it can take upwards of 5 to 8 gallons to get it started again. It was written up in a GM TSB. Two gallons won't start it. When the gage reads less than 1/2, it's not a good idea to park with the front lower than the rear...unless you carry a full 5 gal. refill. Thank you GM engineering.

HAVE YOU TRIED CHECKING THE FUEL PUMP RELAY

Hi ! a easy way to possibly help this is to get a can of sea foam at the parts store and dump it in your tank it may help dissolve any goop that is in there and it helps renew bad gas ,also if this does not help remove your fuel filter and blow through it it may now have gotten a bit gumped up ,not a bad idea if you havnt done that for a few years anyway ,mostly the sea foam should help!

Try replacing the fuel filter first and the primary fuel filter screen in the fuel pump may be dirty also. As for the the one in the gas tank which is a part of the fuel pump, your just going to have to keep the gas tank half full and add some fuel injector cleaner to the gas tank for the next feet fill ups. As for the fuel filter along the frame rail on the drivers side, they have a life of 30,000 miles or 1 year and needs to be replaced within those recommended intervals. Good luck and hope this helps, Note: the gas is what keeps the fuel pump cool, so low fuel in the gad tank will have the fuel pump run hotter causing it to fail prematurely. 

Put the gas in the tank, let everything settle, turn key off, then back on to on position, but NOT start. Let the fuel relay engage the pump and draw some gas pressure. Give it a good minute and it'll start right up.

sounds like a throttle position sensor. or perhaps a mass air flow sensor. let me kkow [email protected]
