A fuse will blow for 2 reasons . 1) If the device has a Short in the circuit that runs through this fuse. 2) If the device draws more amperage from the power source through the fuse than the fuse will handle. ex. if a fuel pump or starter has a 20 amp fuse and the starter/fuel pump is going bad and draws 30 amps it will blow the fuse. A fuel pump on a 1996 vehicle is located in the fuel tank and is kept cool by the surrounding gas and the gas that flows through it. Overheating a fuel pump is virtually impossible. That being said there is a High probability that replacing the fuel pump and relay will fix this problem. It is quite common for this to occur in the GM vehicle of 1996. When the pump starts to fail, it draws an excessive amount of amperage and would blow the fuse. Hope you find this information useful.
