Hello! I recently purchased a 2004 rx8, the guy who previously owned it had built it to race on a track, with that it has a fuel switch. The car at first wouldnt start when hot but I went through and cleaned the spark plugs and now it starts every time, but sometimes it has trouble and floods, I do not think its the plugs, coils, wires, battery, or starter (might be starter not entirely sure) when I start it, I let the engine run a second or two then flip on the fuel switch however it sounds like the engine is trying to catch up and when it does eventually start, white smoke comes out of the exhaust but then it runs fine. I cannot figure out whats wrong, the engine is pretty much new aswell as most of the parts in the car, however the car did unfortunately sit for a good bit before he sold it. Pls help!

P.S. Engine pressure is 130

 

P.S. Engine pressure is 130

im guessing you are talking about engine compression. how was this determined? a rotary specific comp test is 7#s, 3/rotor times 2 and the cranking speed. white smoke could be a coolant issue. is the car de catted? what starter is in it? can you get some pics of the fuel switch?

 

Welcome to the adventure
Can you eliminate the fuel switch?
Dying coils give no symptoms and kill engines, so unless you're certain the coils are new and functional, do not assume it's not that.
If you tested compression with a regular piston tester, you only measured the highest face on each rotor. You need a proper tester to measure each face.
Is the white smoke condensation? Coolant? Oil? Does it happen every start or only after the car sits a while?
How is the fuel pressure? What intake is installed? Can you check fuel trim data via OBD?
Is the engine actually new or rebuilt? If rebuilt, by whom?
