Just recently bought a 2005 RX8 that was working fine for about 3 days until my wife moved it to park one morning and now it won't turn on any longer. Pretty sure it's flooded considering everything that I've read and watched on the internet. Going to try and deflood it myself tomorrow using this video guide.

If this doesn't succeed I will need a mechanic to take it to. Any mechanics in the Raleigh area that could do this with a history with it

Read the posts starting with #465.
Flooding can be tricky, but once you figure it out, it's not very hard to get it started.

Good deal.
Thanks for the update.
Now you need to find out why it flooded.

It wouldn't be from my wife's cold shut off?
I thought that is what it was.
Thanks for telling me to keep looking so I can prepare and investigate

It's a symptom of a problem.

A healthy RX8 won't flood.
Go get the OBD scanned for faults at Auto Zone or other parts store, it's free.

Usual suspects are bad coils, plugs or wires, they cause misfires, dumping raw fuel into the exhaust that damages the catalytic converter.
A clogged cat can kill a Renesis engine.

Simply put, misfires kill cats, bad cats kill engines.

You need to see if you still have a catalytic converter, and get it inspected.
They failed so often, many of them have been hollowed out.

​It's possible that all these have been changed trying to fix flooding problems, but it could already have a bad cat or failing compression.
Those cause flooding.

If the ignition components checks out, then the charging system is left.
Check battery, be sure the terminals are clean & tight.
Corroded or loose grounds happen too.

Don't get discouraged, a lot of things that cause problems are easy fixes.
Other specific things that you should know are about the MAF & ESS sensors.
They can cause a lot of problems when they just need cleaning.
