Question about 2005 Mazda RX-8

Open Question

Where is the fuel pump fuse for the 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?

SOURCE: 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.

SOURCE: I have a 2004 mazda rx 8. I went out to crank it

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.

SOURCE: I need to replace the 100 amp fuse for a '92 Mazda

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.

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

2004 mazda wont start, blew a front tire and had to be put on rollback. Sat all nite, and now wont start. will crank and can smell fuel.


flooded engine common problem remove all plugs and fuel pump fuse. get fuel out of engine do not istall fuel pump fuse re install all plugs I suggest a good charger be used as system can kill batt very quick run to wires from fuel pump fuse into seating area start cranking the engine over wires not touching once compression sounds alright touch wires to geather (may have to repeat these deflooding wire touching procedure many times) once started do not turn off car till normal operating temp . Once hot turn car off remove wires and re install fuel pump fuse .With RX-8 u cannot just start and stop car right away as in washing car as it can produce this same condition ALWAYS let car warm up before turning off.

2005 mazda rx-8 automatic will not start


Does it actually crank? If so and doesnt start then its probably flooded. Been a problem with those cars since they came out but not to feel bad theres quite a few cars that flood easy do to certain sensors. If not turning over but just clicks then battery issue just keep in mind every time try to start and it doesnt that more fuel enters the system and doesnt burn off which means more flooding (to much fuel)

Moved my rx8 yesterday.i got ack in it this


verify condition by spraying some starter fuel in it.it should start and die if its a fuel problem.
if it still does nothing start checking any and all fuses.if all the fuses are good take out a spark plug and verify no spark.
if no spark check the ignition module.
it might be able to have it checked at autozone for free.but you will have to remove it.
