2002 chevy s10 need help

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

You know what the problem is (fuel pump isn't getting power), now you need more details. Sounds to me like you need to get a set of schematics that cover the vehicle. One source is

the fuel pump is electrical and will have a fuse somewhere. replace the fuse. don't mean to sound sarcstic, but is there fuel in the tank? you would be surprised if you knew how many times this happens. the fuel pump should ground itself or have a ground wire when installed. ALWAYS check the simple stuff first!!!!

turn key on and check for 12 volts at pump relay. use a jumper wire if no voltage found and see if it runs. if so, you are losing voltage supply at some point.. while supplying jumper voltage, why not jumper the ground also to make sure you have a good one? good luck.
