where is the fuel sending unit and the starter relay?

the sending unit is in the fuel tank,part of the fuel pump module assembly.the sender lets you know how much fuel is in the tank..get a helper,remove the gas cap,have helper turn key to ON,NOT START while you listen at filler cap..each time key is turned to on,the fuel pump runs/primes for 2 seconds and then turns off.refer to your owners manual for relay and fuse positions.
