Starter Woes, Stumped - Starter Won't Work Options

[Mblizzard]

So my car won't start using the the key. Replaced the switch at the ignition but all I hear is the relay on the fuze panel click. Swapped relays and no change. Have push button wired in that works fine so I know all of the mechanical and electrical connections are good at the starter.

What am I missing?

Ed, from tangerine racing showed me a simple trick.

Put car in NEUTRAL

Take a quarter, remove the yellow wire from the terminal at the starter.
Touch the quarter to the large positive lead from the battery, twist it over to touch the small male spade bit that was covered with the yellow wire.
See if the starter turns over.

If yes, it's wiring.
If no, it's either the starter, or possibly battery cables and grounds.
