No fuel to carb after replaceing pump - S 10 Chevrolet Cars & Trucks

remove the lift pump and make sure its not on the back of the cam ,it will never work like this ,then remove the pipe from the carb end and try putting some fuel down it to prime and wet the valves inside the pump ,if that doesnt work check for a porous pipe froim the tank to the metal pipe that runs to the pump ,if that doesnt work then look inside the tank ?

Hi phcr7566...

Disconnect your fuel line from your carburator and put a container to catch the fuel as you crank your engine...
You are doing this to make sure you are getting fuel to the carb from the new fuel pump you installed...because you might be "air bound"...not allowing the fuel pump to pump fuel to the carb.If your getting fuel to the carb, them make sure the float in the carb is not stuck and not allowing any fuel to get to the engine.
Please rate me

when carb is wide open ????? No carb ,fuel injection ???? Are the injectors being controlled by the PCM / ECM ??? Have replaced fuel pump, fuel filter and fuel pump relay.???? Did you test first ?

Check and make sure there is power going to fuel pump.Turn key on as you test wire (at pump)

have the carb rechecked that the float is correctly set and valve is not worn or debris and fuel pressure between 7 to 10 lbs

Fuel pump electric? Check the oil pressure sensor/switch

SOUND LIKE STOP UP FUEL LINE.OR SOCK IN FUEL TANK STOPPED UP WITH RUST AND DEBRIS.YOU COULD HAVE A WORN FUEL PUMP PUSH ROD OR CAM SHAFT LOBE WORN WHICH DRIVES THE FUEL PUMP PUSH ROD.

Even if that was true, the car would run for 20 seconds without any fuel in the line, because the carb would have gas in the bowl. Why was the fuel pump replaced? How do you know theres no gas in the line? The check valve in the fuel pump should keep fuel from going backwards into the tank. The carb should hold gas, if not, find out why.

try a fuel filter first.if not the filter,you may need a fuel pump or the wireing to it replaced or repaired.

unfortunatly you are going to have to run new power and a new pump. a fuel injection pump runs 30 psi minimum some of them quite a lot higher than that. a carb cannot have more than 7psi without bypassing the float in it and overflowing the carb with fuel. when going to a carb you will have to get a low pressure fuel pump and completely rerun the fuel system
