Question about 2005 Mazda RX-8
Engine will crank and crank but will not turn over, Have already tried the flooded car attempts mentioned in the manual. Checked the spark plugs and all the fuses
Had the same problem today with flooded engine. I tried new plugs ($86.00) and used the clear flood mode but to no avail. Spoke to a tech at the mazda dealership and odd as this sounds it worked. On the right side of the engine on the intake about half way down the runner you will find 2 rubber plugs that cover vacumn ports. The front one is the easier of the 2 to access, hook up a piece of vacumn hose to that port, on the other end you need to hook up a funnel. You will have to adapt the hose up to get it to fit. Remove the fuel pump relay, it is the blue relay at the front of the fuse box and is closest to the radiator. Pour a half to 3/4 quart of transmission fluid in the funnel and have someone crank the engine(with a battery charger or jumper cables hooked to your battery so you won't run the battery down). Leave throttle closed, as the fluid gets sucked down you will here engine compression build and it will act like it is going to start, at that point while it is still being cranked stick the fuel pump relay back in. It should then start, it may spit and sputter but it will run. Remove the hose from the vacumn port and reinstall port plug. The car will smoke for quite awhile but the smoke will finally disipate. From start to finish it only took about 2 min. to get the car started. I asked him if that much fluid would hurt it and he said no. He also said that they see this problem a couple of times a week. He also said that they don't take the plugs out and clean prior to doing the procedure, it will work on the old plugs. This saved me a tow to the dealership and probably a couple hundred dollars.

spark is produced by the distributor module that sends the current to the coil pack/packs

I had the same problem today. what i did nd was told by a local performance shop was to take off at least 1 leading and 1 trailing spark plug on one side and just disconnect the wires on the other two spark plugs. Then u crank the engine a couple of times until there is no more gas in the chamber. You then just put back on the spark plugs and the wires and crank the engine. The car will then turn on! (note) There will be alot of smoke coming from ur mufflers but will then go away! its normal.

Here was a recall on quite a few 2004 RX8 cars. There is a part to be replaced free by a Mazda dealer that is supposed to fix that problem. I had the same problem. However, it doesn't totally fix the problem. The service mgr told us to drive the car for at least a mile if we're going to move it for any reason after it has cooled down. Moving it short distances while it is still warm doesn't cause the dead car problem. He also suggested that we reve the engine up before turning it off to burn off the excess gas. That has worked, and we've only experienced the problem once recently. We had to push it out where the direct sun would shine down on the engine, lift the hood, take the engine cover off, and let the excess gas evaporate. Then the car started fine.
