I have a 2000 VW Golf and am having problems starting it. I had the starter checked it was fine I was told that the ignition was bad so I replaced it, the car still will not start. Now they are telling me it is the relay but no one can tell me where the relay is

This is ignition switch. I had the same problem. I replaced and its fired up right away.

Will not blame anyone 1st have you checked the black fuse box under the hood?if not,then look for main relay box(black) remove the cover,then look under the cover lid for relay locations. find starter relay.have some one Put their finger on top of the black square starter relay,then you turn your key switch to "on" does the relay that the fingers on click? if so,its'good. you also have what garages call a fuseable link.it's a hard black peice of rubber thats located in between the starter and the battery. but 1ST LETS COVER THE MAIN ISSUES WITH NO START! IS BATTERY FULLY CHARGED?A MUST! WHEN YOUR CAR IS ALL THE WAY IN PARK AND YOU TURN THE KEY TO START,NOTHING AS MUCH AS A CLICK? DID YOU HEAR A CLICK? GO TOWARDS A BAD STARTER CONNECTION,OR BAD STARTER.ARE STARTER BOLTS TIGHT? IS BATTERY TERMINALS TIGHT,THINK I ASKED THIS EARLIER BUT JUST 2 B SURE.
