spark plugs anyone? help!

so i'm driving my fathers 2003 4x4 chevy silverado 2500 HD and he says if i find where the spark plugs are and can show him where they are and maybe take them out i get $500 and considering i already owe my parents 700 dollars at the moment this would be great! so anyone want to help me....walk me through it on here or take pictures of your chevy showing me where they are?

Welcome to AF, is it a diesel? If so no plugs, you lose. Otherwise follow the wires.

thanks for the welcome and yes its diesel and i think i may have to shoot my dad haha just kidding maybe i'll try and trick him into letting me have the money and act like i know where they are =]
