Engine rolls over does not start


I had this problem. Twice! It sounded like it wanted to turn over but couldn't. Your engine may be flooded. I had to have mine towed to the mazda dealer (if under 100,000 miles it is under warrenty) so they could fix it. The second time they had to replace my engine because of a bad compression ring.

Mazda rx8 flooded .brakedown come tried to start engine turned over !then starter got hot ,now dosnt turn over just clicks? any wdvice please


Your problem is common in the RX-8. It occurs when you start a cold engine and shut it off before it reaches normal operating temperature. If your car does flood, you can first try depressing the accelerator completely and holding it (which shuts off the fuel pump) and then crank the motor for about 10 seconds (not longer or you may damage your starter). If this procedure above does not work, here is the technique a Mazda dealership will normally use (to be performed at your own risk): 1. Use jumper cables to connect to another car battery. 2. Unplug Air pump connector (the black circular motor housing to the left of the oil filler cap) 3. Take fuel pump fuse out (number 22, a 20 amp, 3 from the top of the second column of the fuse box 4. Crank for 4 seconds, pause for 2 seconds, repeat for about a minute 5. Leave for a minute 6. Crank for 4 seconds, pause for 2 seconds, repeat for about a minute 7. Put fuel pump fuse back in 8. Crank for up to 10 seconds, if it catches but doesn?t start, stop cranking 9. If not started go back to step 3 10. If started, wait 30 seconds for oil pressure to rise 11. Stand on throttle until white smoke stops coming out of the exhaust 12. Disconnect jump leads 13. Leave to warm up on idle for a few minutes 14. Put air pump connector back on (see note 3) 15. Go for a nice long drive to recharge the battery

RX-8 rough starting under all conditions


if u happen 2 have an amp and subwoofers it will drain ur battery over time without a compasitor.as far as the screeching try rubbing a bar of soap on the inside of the belts while the car is off.also check spark plugs are at the right gap specs.

Rough start and misfire


first of all you say you took out the plug you may have to replace the boot on the #2 spark plug and where you said it is fill with gas look at all of you injectors on that side and the fuel rail to make sure nothing is leaking at all use a flashlight when trying to find the leak cause its safer that way.

Mazda 2005 RX-8 wont start... ran yesterday, lights on & sounds


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.
