fuel pick-up in tank is blocked it has a sock over the end as a gross filter to keep out any big junk from getting sucked into the pump and causing damage to it. the sock can get so plugged up that no fuel will flow, causing the pump to run for a short time then with no fuel flow to cool it it trips the safety and shuts off
might be a bad fuel regulator.. or your fuel pump relay might be going bad.. and also where did u get your fuel pump from.. i ran into a problem where i had to replace a fuel pump 3 times before i finally got on that worked right..
if you can put fuel in throttle body and it runs. then it is not getting any fuel. check your fuel pump fuse and the relay, if ok, then you may have a bad fuel pump or a plugged up fuel filter. check filter and fuses first. good-day !!
before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.
Have you changed the fuel pump yet?I had the same exact problem.I replaced my fuel pump with an AUTOZONE PIECE OF JUNK fuel pump.That pump lasted almost 2 days.The second day i had it the truck didnt want to start but it did and it ran like ****,and when i put it in gear it ran as long as I didnt touch that gas pedal.You could go get a fuel pressure test or just replace it,your call.You might want to check your filter too but im sure its the pump.Good luck
Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.
Did the problem start when the fuel pump was replaced? It could be some kind of obstruction in the fuel line or a fuel filter acting up - needing replaced, or the filter on the fuel pump somehow didn't get installed correctly. Spend $20 and get a Haynes Repair Manual from Auto Zone to show you step by step instructions with pictures how to troubleshoot just about anything for your make and model.
