2008 chevy express 3500 6.0 fuel pump no power was driving it and it just quit replaced pump still nothing just cranks over

2 of them........First Fuel Filter

One fuel filter is in the fuel pump of the Express Chevy 3500, which is used to push fuel or gasoline through the fuel line. The fuel pump is inside the gas tank. This fuel filter is a mesh or screen that prevents large foreign particles for entering the fuel pump. Access to the fuel filter is obtained by removing the fuel tank and then the fuel pump from the fuel tank.

Second Fuel Filter Location

The second fuel filter is within the fuel line itself. After the fuel pumps extracts fuel from the gasoline tank and into the fuel line, fuel flows through the line and through another filter on the driver's side of the Express Chevy 3500 under the front wheel suspension. This fuel filter cleans the small particles that escaped from the fuel tank.

Fuel Filter Types

The year of your Chevy Express 3500 determines what type of fuel filter is installed on the van. The fuel tank filter is always mesh or screen, but the fuel line filter can be of three different types. Two types are snap-on filters, while one type has clip-on ends.

Has the fuel pump relay been tested? Be aware the pump only runs when the engine is being cranked over with the starter.

are you sure it is not a fuel problem,check to make sure that your getting fuel,could be the solenoid on the fuel pump,does it smoke as your cranking it.

check the fuel pump relay and fuse.

Hi...sounds like you might need to replace your Distributor Magnetic Pickup !

Hope I helped!

There should be a fuse relay box under the hood with a fuel pump relay in it...have someone turn the key while you touch the relay to see if it is clicking when you turn the key..if not replace relay....if it does click, then it may be possible that the contacts on the relay are defective and the relay will need replacement anyway...there may also be a fuse for the fuel pump either in this box of under the dash...check to see that it is good also.

did you try to replace the fuel pump relay ?

CHECK YOUR CRANK SENSOR AND CAM SENSOR.

THE CRANK SENSOR IS LOCATED RT UNDER THE CRANK PULLEY. IT IS USUALLYEASIEST WITH AN EMPTY TANK TO REPLACE IT.
