need help 2002 chevy s10

My cousin has a 2002 chevy s10. It wont start we put a new fuel pump in it they told him it was bad and a new relay. It still has no power to the fuel pump.Gas guage will move with the key off but as soon a you turn on the key it goes to empty. We was told to check the grounds but dont know where they are located plus he was told it could be the ingintion switch. If you spray ether in it will start. Any suggestions on what to do. Or what else to check thanks

Determine down there if it is the 12volt wire that is out or the ground. It help to have wiring diagram to see where the next temination point is with those color-coded wires, and then test at the next connection point upstream, etc. Not much else one can do. Can't just guess when it comes to electrical. When testing with a meter, always make sure your meter is working by testing something else.
