hey guys my rig wont start. i turn the key to cycle the glow plugs and after the wait to start light goes off i turn the key to start and i get nothing, the wait to start light comes on again and no sound, no nothing, i checked my fsm and ive gotten as far as checking the battery its good. and the terminal connections there good... i took apart my ignition switch and checked the connections and everything seems to function perfect im thinking its the ignition relay or something please let me know what you think thanks for your time.
