A long crank before the engine starts, sputtering or a whine from the tank can mean a weak fuel pump assembly. These signs alone do not prove the module is at fault, since a blown fuse or a bad pump relay can look much the same.
Fits
The same module also fits the 2010-2013 GMC Sierra 1500 V8 4.8L, 5.3L or 6.2L, and either truck takes one.
