You should go to www.reliable-store.com they have got books on every vehicle and also how to service/repair it, parts info, fuse box, gear box, torque specs,coiling, wiring diagrams, electrical diagrams, fuse diagrams, error codes, etc everything

sounds like a mouse has got in and chewed the cables,their is no easy fix from what i can think of but check all the wires and connections in case water has got into it,or snow if your in alaska.its fifteen years old now so its possible that some insulation has broken down or a wiring loom has chaffed somewhere underneath

Obviously power is being drawn by something, perhaps motor is stuck, shot , or switch is faulty. If you can get to motor wires & test for voltage, even by poking with a test light. There should be no voltage to motor on either wire, until switch is pushed. It will supply voltage to 1 wire, then the other, when switched to opposite direction. just reverses polarity. The switch may be faulty & supplying voltage to motor, and telling it to rotate in direction that it has already went as far as it can.

If this was not a problem before the pump replacement then the sender in the tank may of faied or is contaminated with sulfer which is corrosive to the silver electrical contacts.
Do a search on sulfur corrosion and fuel sender units. Gm has big problem with this. Its possable the stress from removing the old and installing the new pump created an issue with contacts. If this is the case you will now need a sender unit.

Common problem on the 03-06 Silverado instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out.
