Where is reset button for feul pump for 2001 GMC Sierra 5.3

Its on the bottom of the gas tank. Gotta hit it real hard with a big hammer. Not the pointy end

I could be wrong, but I do not think that there is a reset button. .Check to see if the fuel pump relay under the hood clicks when key is turned from off/on if so check the 20 amp ECM B fuse. If fuse and relay clicks then check grey wire leaving fuel pump relay for voltage when key is in crank position. If voltage at relay but no voltage at pump run a new grey wire....If relay does not click make sure black wire going to relay has good ground and dark green/white wire is provided power by PCM to activate relay.
