How do you change fuel pump in a 97 chevy s -10 4.3 liter need help fast and if possible show where the places the relays are and fuses

The fuse is under the hood on the drivers side inner fender their is a fuse box their.If you have power their then check power at the fuel pump relay which is located in the glove box on the passenger side inside the vehicle,there is a cover in the back of glove box remove the panel and their is 3 relays their you should feel the relay clicking for about 3 seconds when you turn the key on. Check for power their if there is power their then you must check for power at the fuel pump. ZThere is a connector right on top of the fuel pump on top of the tank,you should be able to get to it from under the truck without removing the tank.The common cause on these trucks is the connector on top of the fuel pump melts and causes an intermitent problem. if you have power their for about 3-5 seconds this is OK. You must then replace the fuel pump.It is fairly easy on these trucks. Drain the fuel if you can then undue the 2 hose clamps on the filler and vent tubes,then you put a jack under the fuel tank with a piece of wood on it and remove the 2 fuel tank strap nut and bolt, lower the fuel tank and then remove the fuel line carefully do not break them they are hard plastic lines they can brake easily and be costly then remove from under the truck.Take the time to clean around the fuel sending unit and pump to prevent dirt from getting in the tank and causing lots of problems.Remove the retaining ring with a screwdriver and Hammer,and the pump assembly will pull out. Replace the pump assembly and reverse the procedure for install.They usually supply you with a new wire connector when you buy the new pump USE IT. Remeber to replace fuel filter at the same time. Hope this helps
