2004 RX8 won't start
Need some help. I have a 2004 RX8 that will not start. She has 48,000 miles. The was running great. I got in an accident and and she has been in the body shop for about a month. When they went to pull her out if the spray booth she cut off and would not restart. She just rolls over. Any Ideas?

Extraordinary Engineering
Check the de-flood threads
Checking the plugs will tell you.
Steps:
1) Fully charge car battery
2) Replace old slow style starter motor with upgraded starter motor (04 and 05 models).
3) Remove spark plugs
4) Disconnect ESS this prevents the plugs firing. (this might produce a CEL P0335 Eccentric shaft position sensor circuit problem ON 1 CCM ´
(See DTC P0335 )). I guess you don`t really need to do this but there is going to be a lot of gasoline vapor.
5) Unplug fuel pump fuse.
6) Remove all the spark plugs
7) Dry and clean around all the spark plug holes. Doing this to give us an indicator of when the engine has evacuated all the fuel.
8) Depress fuel pedal to the floor and hold it there while cranking engine
9) Crank engine for 5-7 seconds. Make sure not to over heat the starter and allow it to cool for a minute between cranking cycles
10) Inspect spark plug holes. They will likely be covered in moisture. Dry and clean.
11) Repeat this cranking procedure 10-12 times or until not vapor or moisture is noticed during cranking. Make sure to keep the battery charged up or switch to your spare.
12) Put everything back together. Fully charge battery.
13) Start engine, have fun

I'm not a fan of that deflooding procedure for new owners...
This is the one that i recommend for new owners, since it doesn't involve a single tool (other than jumper cables), doesn't require any knowledge of where stuff is in the car, and is really simple to follow:
This is the one that i recommend for new owners, since it doesn't involve a single tool (other than jumper cables), doesn't require any knowledge of where stuff is in the car, and is really simple to follow:
1 - Hold the gas pedal smashed to the floor, keep it there
2 - Crank the engine for 5 seconds
3 - Let it rest for 5 seconds
4 - Repeat #2 and #3 10 times
5 - Let the starter rest for 30 seconds
6 - Repeat 2 through 6 again
7 - Take your foot off the gas pedal
8 - try starting
If it doesn't fire up, repeat 2 through 8 again.
If it coughs and chokes but still won't fire, repeat again. If no hint of starting, then you are going to need to shift to a different deflooding method, because you are probably reflooding it immediately again.
Keep in mind that you will need to determine why it flooded in the first place. You can shut the engine off cold with no risk if your battery, starter, engine, ignition coils, plug wires, and spark plugs are all in good condition. So since it flooded, one or more of those parts is failing. Ignition parts need replacing every 30k max. You should have a decent idea of how the battery is doing from day-to-day use. If those are new and you know that the battery was in good shape, then take the car to the dealer for a compression test. That will give you the health of the starter and the engine.
