2000 z71 5.3 will crank but goes dead as soon as it does changed fuel pump and filter getting gas to injectors but I can put a rag with gas on intake and it will run till fumes run out has me puzzled...


If it runs when you out gas into the intake, but not when you don't then most likely the injectors are not getting the gas they need, or are not injecting it properly, or at all. Could be a bad pressure regulator. I'd suspect the fuel system, check it thoroughly.

97 jimmy runs when you pour gas into throttle body, fuel pumps is putting out 55 to 56 psi. but will not pickup the gas from the injectors, fuel manifold psi is 55 to 56psi. 1997 4.3 vortec engine


If the 8th letter of the VIN # is W which i bet it is than your fuel pressure is to low.

This engine uses a CPI unit to deliver fuel to the cylinders. The CPI unit consists of a central injector that feeds fuel to the poppet valve that are right above the intake valves. The poppet valves require high fuel pressure in order to open and deliver fuel to the cylinders at start up.

The reason why it starts and runs if you add a little gas through the throttle body is that once the vehicle is running the intake is under vacuum. The poppets can open with less fuel pressure in a vacuum. This is a real common scenario with these style injection systems.

A new good quality fuel pump (a/c delco or delphi are good pumps) and your fuel pressure should be back into spec of 58 psi or more and the vehicle should fire right up. Make sure you replace the fuel filter when you replace the pump.

Ran out of gas. Put gas in it started right up then after a few minuts it shut off. Put gas in carb it runs till gas is used up. Where is fuel filter and is the fule pump in gas tank?


Fuel filter is located on the inside frame rail under the drivers door and the fuel filter is located in the gas tank. Start with the simple and change the fuel filter first, but it is common for the fuel pump to burn out when the gas tank has run out of fuel, but since your engine started back up. Good chance that your fuel pump may still be good and your fuel filter may have pick up dirty from the bottom of the gas tank which is causing your engine not to get any fuel.
Thank you for using fixya and good luck

1997 Safari will not start unless carb cleaner sprayed in air intake. runs after this. Confirm spark and motor rotation.


Have your fuel pressure checked.Sounds like pump or relay is out or fuel filter restricted too much.Remove the gas cap and put your ear to filler neck while someone turn's the key on,you should hear the pump running.pump run's for about 8 second's to prime fuel rail then shut's off till cranking.

HHR LOST POWER AND SHUT OFF. IT STARTED RIGHT BACK BUT WHAT CAUSED IT TO STOP.


Going to keep it simple since it started up again and is running, Chances are the fuel filter has come to the end of it's life and needs to be replaced. After saying this you may get away with filling the gas tank a few times and adding fuel injector cleaner to the gas since the new style fuel pump with the filter is also know as self cleaning filters and is good for life till the electric pump fails it self, which has an average life of 150,000 miles. You can get more life out of the pump if you run more then half a tank of gas always, the gas it self is what keeps the electric pump cool and less gas means hotter running fuel pump. 
GM has stopped putting in-line filters in some models since 2004. Other manufacturers have been doing it longer. The fuel sender assembly (pump/regualtor/sock/level sensor) inside the tank has a container on the bottom of it about the size of 1/2 coffee can. All the fuel pick up components are inside of this container. It has a small intake port in the very bottom that filters the bigger debris so that the fuel that is filling the container is fairly clean. The fuel fills the container and a sock(filter) is used at the end of the fuel pumps pick-up tube. Smaller debris that makes it to the sock is then filtered by the sock before entering the fuel pump and simply falls to the bottom of the container.

Todays pumps are much more robust then pumps of old also. We still see more failures of the old style pumps with in-line fuel filters then we do of the newer style. GM calls this a self cleaning system. Any debris that does not go into the canister of the fuel pump assembly falls to the bottom of the tank and any debris that the sock stops falls to the bottom of the canister when the fuel pump is shut off. We are talking very small amounts of debris here too.

Good luck and hope this helps and like mentioned, try running the HHR with more then half a tank of gas and adding fuel injector cleaner for now.

Fuel isnt coming out hte injectors


ok when you turn the key on, you hear the buzzing sound in the tank? if you spray starting fluid into air intake, will the engine fire? there should be a fuel pressure port under hood on fuel rail i believe. if this is vortec style engine, injector assy under intake is possible. somewhat common. pull oil dipstick and smell for fuel. that would indicate maybe the pressure regulator has let go. ck for spark as well, just to be sure youre on the right track.
