Question about 2005 Mazda RX-8
I have a 2005 RX-8 and I think it is flooded. I read that you can take the fuel pump fuse out and crank it a few times and it will empty the cups but I don't have my owner's manual and I don't know which fuse is for the fuel pump. Any ideas?

I have a 2004 that had the same problem. It sounds like the engine might be flooded. The best thing to do is to remove the fuse to the fuel pump. It will be listed under the fuse cover under the hood. Mine was a 20 amp but check to be sure. With the fuse removed, crank the engine for a minute to remove any fuel flooding the engine. Replace the fuse and crank the engine in 10 second intervals without touching the gas or you will reflood the engine. This process can sometimes take awhile and will drain your battery, so have it connected to an additional power source ( i.e. another car battery or jump box). When the car finally cranks over there will be a huge cloud of smoke so don't be alarmed when it happens. Lastly some words to the wise. This process CAN ruin your starter, but is essentially the same process that the dealership will you except that they will remove the spark plugs to drain the fuel and then charge you for new ones. If this process doesn't work then you probably need new spark plugs which is going to cost quite a bit. I was quoted upwards of $525 to fix this problem until I talked to a Mazda mechanic and found out how to do this myself. Just make sure that the engine is up to running temperature before turning the car off and you shouldn't encounter this problem again. I hope this helps you, and remember that if all else fails the dealer can fix it. It won't be cheap, but they will get it done.
I almost forgot, you HAVE to get the oil changed as soon as possible because there is probably gas in the oil now.

Yes... it sounds like it is or was flooded. One of the list of things I do not like about my RX-8. Fun car to drive, but it has so many little goobers like this flooding problem, the car is not practical.
To unflood, google the procedure for unflooding Mazda RX-8. It takes some battery power, but it does work. In a nutshell, you pull the fuel pump fuse, and crank the engine over intermittantly for a number of times with pauses in between.

Hi, The biggest fuse to be replaced is a 30amp. I don't know what you have that is that big. Could be a relay you have. Usually under the steering wheel and left. Good luck.
