1986 Chevy Silverado Started, Stalled now wont Start

[bobbi.wudwudandrew]

Started the truck just fine this morning, walked away for 5 minutes came back and it had stalled and now wont start up again.  Tried carb cleaner...it started and stalled again.  Tried pouring gas into the carb...started and stalled again.  Wont stay running for any length of time and after it stalls it wont even attempt to turn over again.  Any suggestions??

When you say it won't attempt to turn over again, do you mean it won't start or it won't crank?

you got fuel in your tank? hows the fuel filter?

     First thing make sure Carburetor is getting fuel, take supply hose off and put in a bottle or something to catch the gas, have someone crank over your truck for 3 or 4 revolutions.  If it pumps out a good amount of fuel, you have eliminated everything before the carb. 
     If it does not pump or pumps real slow, then the first problem that needs to be addressed is supply, meaning is there fuel in the tank, is the supply hoses's not collapsed so as to allow enough fuel to get to fuel pump, make sure your fuel pump is still pumping fuel, weather it is a mechanical or electric fuel pump.
     If it is pumping a good amount of fuel (enough for the carb to keep up with a idling truck), then the problem remains in the carb.  It might be time for a rebuild, the float, needle assy, or other common items may be getting stuck, which at this point your best bet if for a rebuild.
     Check out these few things and report back if you have not been able to correct the problems and we can go from there.
