CHEVROLET TAHOE FUEL PUMP PROBLEM

1997 Chevrolet Tahoe • 160,000 miles

Fuel pump turn on when key is on then shuts off after a few sec. But turns back on when started and don't shut off? When I drive it sputters like it don't get enough fuel then stalls but starts back up? Fuel pump is new.

With the engine off, it should only run a second or two when you first turn the key on. As far as running with the engine on, that is normal too. Have you checked the fuel pump pressure at the fuel rail?
