I got the vehicle listed above less than a week ago and it was running fine. Now it won't turn over. Replaced plugs, wires, distributor, cap and button and fuel filter. Still won't turn over.

Hello,

Just to clarify, the engine cranks over but not starting right?

This could be either a fuel or spark issue. Have you checked to see if you are getting spark to the plugs?

How about fuel? Does the fuel pump come on when turning the key to the on position?
An inoperative fuel pump can be due to a bad relay, wiring issue or a faulty pump.

Take a look at this guide, it covers the typical crank no start issues.
Go through this and report back to what you find.

Let me know if you have any questions.
Thank you.
