No fuel coming from the new fuel pump but can hear it running

dont understand fire coming in and going out? its possible the new pump is bad. Pull the fuel line off and blow through it into gas tank and listen for it to bubble take off fuel cap so you can hear it better. if you can blow through it then u know its not blocked.on the line going to carb replace the filter .if it still dose not work , with the ignition on tap on fuel pump and listen to see if u hear it running. If it dose or dosent should replace it again. Unfortunate as it is.

There should be battery voltage at the fuel pump. Check the battery voltage at the fuel pump relay to be sure that there is power coming from the battery. Check voltage at fuel pump fuse.

It could be the fuel pump or just the fuel pump relay, try reseting the relay / breaker on the top of the firewall. Also have someone lister at the gas tank with the cap off when you turn on the key and see it they hear the fuel pump come on. Chevy's have loud pumps and are easy to hear. If it doesn't come on, try the reset or you may need a new pump. Sitting on its side could have run it dry and cause it to go bad.

Check the fuel pressure regulator at the fuel rail or throttle body.

If you have disconnected the fuel filter (inlet) side and turned on the ignition, if fuel is not coming out of this line, then there is a fuel pump problem. This is assuming that you can hear the fuel pump actually running. Usually when the fuel pump runs and you can hear it, then there can be a screen on the pump plugged or the pump its self is not working. Hope this helps.

did you check the wireing to the pump? try connecting a battery directly to it, ie..red to possative, black to neggative, see if that runs then if it does you poss have a broken wire somewhere or relay is u/s..hope this this helps

Check all the fuel lines and connections very carefully for leaks and condition. The pump may be drawing some air.

We assume you have the correct fuel pump for the vehicle, that it is operating normally, you have the correct fuel filter and that there are no obstructions in the fuel system as a result of the work carried out so far.

Yes, if you got a good ear. It is common to hear the fuel pump running without the engine. The running sound should come from directly over the fuel tank like it's almost underneath the rear sear. If it is abnormally noisy, ie you can hear it over the engine running, I suggest you install a new fuel pump. This one is probably headed for a failure soon in that case. Regards, Doug

You can Hear fuel running? Where in the tank? If so then it sounds like the fuel pump dettached from the supply line inside the tank.

must be a relay take the relay out from another source and put it in the fuel pump side
