Did I buy a Bad fuel pump???

Asked by Jan 21, 2017 at 09:06 AM about the 2004 Chevrolet Silverado 1500 Ext Cab Short Bed 2WD

Question type: Maintenance & Repair

I Have a '04 1500 and recently had to change my fuel pump. It ran great for
about a week, and then i would go to crank it and i would have to turn it over a
few times and pump the gas for it to start.

Did you change out the fuel filter when you did the pump? You should;t have to pump the accelerator. Check the fuel pressure and test out the fuel regulator.

No just the Fuel Pump I was told that on this model the fuel filter is irreplaceable.

Well who-ever told you that is full of it. The fuel filter is underneath the drivers side door. And what size engine is this, Looks to me it is the 4.3L . Like Tom says, verify the fuel pressure before and after changing the fuel filter. Fuel pressure should be 56 to 63 lbs. up on the Schrader Valve.
