2001 Dodge ram 2500 5.9 v8 won't start. First time

SOURCE: Fuel Gauge Flickers but does not work properly-

there is a fuel senor inside of the tank and it could very well be the problem

you say you replaced the fuse, but does the fuse have power? the gray wire at pump should have power when cranking, or for 2 seconds when turning key on. At fuel pump relay, put power onto gray wire, the pump should run if the wiring is good. if it doenst run then ck for power at fuse while power is on gray wire.
