No start no spark - 2004 Mazda RX8

Thanks guys I thought that to and any advice for stuck cat bolts was gunna buy a nut splitter to get them off?

The car was flooded when I deflooded it went to start it started for about 2 seconds and died tried again but no start and when I touch the gas pedel it does not help

Hey guys finally managed to get my cat off it's all broken up inside so def nackered but I changed a bad spark plug in the 1st cylinder which seemed to make a difference but last time the car started it cut out after about 2 minutes as it would not rev about 2,000 rpm with new spark plug 1,000rpm with old spark plug but now I have removed the cat and O2 sensor attached it will not start at all now and again chugs but I think I may have flooded it, tried to de flood by removing fuel pump fuse turning over and replacing Ect but no joy but it does get the smell of fuel when fuse is out as it it setting ride of some then on the last attempt to start I think the battery is getting low and lights faded then all the speedos went to full and back down?

Do you know why this is and and where I would go from here and maybe the best way to de flood a rx8 if I still can?

Lol the car was not flooded in water the engine was flooded with petrol

Hi thanks for that much appreciated managed to fit the gutted cat back on with new seals and bolts, tried the de flood method and the best I have got is that the car will start and tick over with my foot still on the gas from de flooding but once I remove my foot it just cuts out again, would you know where I am going wrong at all to resolve this?

Hi Guys,
quick question but when deflooding RX8 is it normal for the engine to kinda start but be restricted to under 1000rpm, I mean it ticks over and when I raise my foot from deflood (to the floor mode ) to pump fuel the car chugs then eventually starts but revs do not exceed 1000rpm should I turn off and keep deflooding or should I keep the revs stable and warm the engine up to see if this then improves the revs?
Thanks

When the car is cold it does not start finally did started run fine for two weeks and then did again. What can be causing this. Replaced spark plugs, coils and wires. Is any sensor that should be replaced? Thank you.

Thank you for your prompt response> is there anything else I should check? It seems to me that there is something else that is causing this > the reason I say that is because the car will start and runs great, never had that problem before and then all of the sudden started to do that> drove for the last two years and it never did that. Thank you.

Ok thank you for your help.
