Pull the vaccuum hose off of the regulator. If wet fuel is present, the regulator diaphram is bad.......replace the regulator.

My 2003 chevy silverondo feul pump stops working . have changed feul pump worked good for week and started doing it again. will start up again but who knows when

Did you replace the wire harness from the new sending unit to the frame??the old one tends to break when moved around causing issues and also inspect the ground wire also to ensure that it's still has a great ground on the frame from the harness.

The other thing also is that you may want to replace the fuel pump relay just to make sure it's now faulty. Just swap it out with another relay in the relay box.

Good luck and keep us posted.

1996 chevy s10 4.3 vortex lifters knocking at start up but goes away after 10 minutes idling. changed oil and filter oil pump reads 58-60psi at idle and seems to be working.

High milage? Try engine cleaner, run for couple hundred miles and then use an additive like Restore. If it's just dirt this may help. Make sure you are using the correct viscosity oil for winter temps. If it's from wear only parts replacement will fix it.

1996 GMC Jimmy Need help trouble shooting. Turns over but won't

Fuel pump or injector assembly. Need to know what the fuel pressure is before throwing a part at it. By what you are saying I'm leaning tword the fuel pump. Make sure the wires at the top of the sending unit are not burn. There is a small 4 wire connector on the inside of the sending unit. If it's burnt you will need to replace both the pump and sending unit.
