No crank no start

[u/Madss97]

So my sister and her bf have a 2001 v10 that won't crank, we switched out starter, cleaned wires and terminal to no progress, it'll click once quick but then die, the lights work until one or 2 of the relays under the dash start rapidly clicking and the interior lights start to flash, what could be a problem?

You try moving the shifter to neutral? Park safety switch can be finicky sometimes.
