If you had a strong stream of gas shooting out then you may have an fuel injector problem. Possibly a clogged injector or bad injector.If the stream of gas was weak replace fuel filter first and test again.If problem persists check pump fuse then replace pump. sorry for miss reading your post.

I read somewhere that the fuel pump is lubricated by the Gasoline.It warned to never run out of gas with these Cadillacs.It may need a new fuel filter now.

The junk may have collected in your fuel filter?

Someone posted they had there fuel pump quit after running out of gas 3 weeks later. Try disconnecting your battery for 10 minutes first to see if it is actually the Anti-theft system.

Okay, you need to make sure the fuel pump is getting power and that you have the lines hooked up correctly. Also, when you replace fuel pumps you need to remove the air cleaner and use starter fluid to get the engine started.

Check fuel pump pressure and fuel pump regulator. It sounds like you are not getting fuel into the system and if you are you are not getting enough fuel into the system

1995 gmc jimmy-won't accelerate wants to stall


could be the fuel pump ...you will need to do a fuel pressure test on it ..the pressure should be 63 anything lower even so much as a few lbs will cause this to happen ...as well if it sat that long i would consider a complete tune up and check all vacuum lines for dry-rot

Replace fuel pump-stil no start


Was it empty when you parked it? (i.e. did someone drain the tank, and put sugar in it? something like that?) If not... the fuel filter could be clogged. Check that. Most cars of this age are fuel injected, so the fuel at the fuel filter will be under high pressure. Chiltons manuals usually discuss how to de-pressurize the line if needed. But you probably already dealt with this changing the fuel pump. Good to hear it's turning over. After (finding) the filter... check to see if any fuel is making it through the filter. Turn the ignition to "on" and it will likely start the fuel pump and spray fuel everywhere (if you disconnect the filter output.).... besides having a mess, you will know your fuel pump works. (Try attaching a hose from the fuel filter output to a bucket to prevent a mess and possible fire please ). Can you hear the fuel pump running? Could be a blown fuse for the fuel pump.

Water in gas tank how do i remove it


Disconnect battery,remove the tank and drain it.The fuel pump is no good now too,replace it with new.After draining the tank,let it air dry for several hours so that ALL the moisture has dissipated.After reinstalling fuel tank with new pump,safely disconnect a fuel line up at the engine and place in a container.Add new clean gasoline,and cycle the ignition switch on and off so that the fuel pump will come on and flush the fuel lines of old contaminated gasoline and water.After a thorough flushing,replace the fuel filter with new.Also,add a small can of "Dry Gas" to the fuel tank as this will take any remaining moisture out of the tank.Good luck.
