To be honest I am reluctant on learning how to drive a stick I would be teaching myself and I’d have almost no clue as to what I’m doing and I’d be afraid to hurt my car but I did want to learn everything I could. I have a lot of pride and love in my rx8 and it would crush me to have to trade her in
If you want to go there and restate your issues, it might help.
Good luck!

Over the summer, my son bought an RX-8. It has had the motor replaced and the transmission. The motor has 49k miles on it I advised him to not buy it...but him being 21...he knows more than me.
So, here we sit....car not starting at all. At first, it was not starting when it was hot..had to wait 15 minutes before it would start up again. Now, it will not start at all.
No lights or anything....it was completely dead. I need to mention how he recently had a new battery installed this past July. Nonetheless, we tried to jump it with my car....which did give it enough power for the lights to illuminate...as well as it is trying to start. It is turning over...smoke comes out of the tail pipes....but will not start. Any advice would be greatly appreciated. Thank you

A few things could have happened:
- ignition failure
- fuel pump failure
- engine failure
The problems starting hot are kind of a clue toward that last one but if you want to be certain, get a compression test. Suppose it needs a new engine, are you ready to invest in that?
What kind of maintenance or modifications did your son make during his ownership? Do you know if the ignition coils were replaced in the last 30000 miles? Anything from the previous owner?

He only has bought the new battery....no other modifications. The previous owner told him he had replaced the motor 48k miles ago...and transmission. It appears there were recalls on this model for sealing rings located in the fuel pump.. Would something like that cause this issue?
I don't know if the other owner changed the coils or not....But we have not done anything else to it.
Also, is there a way I can test the ignition coil?

Looks like a spark plug.

Hello
I bought an RX-8 from USA i july and has been driving around a lot. Recently I`ve had some small problems with the car. After I`ve been driving around for a while and stops the car (engine warm - I always wait for the engine to be warm before I stop the car), and if I try to start the car after 1 min it won`t start. Sometimes I have to wait for about 5 minutes, sometimes 10 minutes.
Today I was driving from store to store, and everytime I got out to start the car I had to wait for 10 minutes. I was in a hurry because it was just 20 minutes to the stores closed.
I`m from Norway and there is not many guys here with an RX-8. The car is so expensive here (new price = $150.000) so no one knows much about the car or the wankel engine. I`ve been searching this forum and found a lot of threads about flooding. A while I thought that was my problem, but after reading several people saying that the "engine won`t start"-problem doesn`t happen when the engine is warm, this must be something else I think.
I`ve checked my oil and it`s fine - I check it often. And I always keeps the engine running until it`s warm before I turn it off. And I also redline the car everytime I drive it. I`ve read about all these things that I should do to prevent problems.
So therefor I ask you guys, what do you think causes the engine not to start when it`s warm? It`s very annoying. Could it be the spark plugs?

ohio gozaimas!
Just thought I'd chime in with another datapoint as an "old timer". I've had my 2004 AT w/88k for 17 years now. Up until 2017 it was a daily driver (got a 981 Cayman S as the new daily driver, awesome car). I have been dealing with the "hard start while hot" for probably 12 years now. Yes, seriously. The initial problem was solved because of bad batteries, but it has resurfaced and it's not the battery this time...
Yes, it's obnoxious. I used to go to the dealership, and they were useless. Got a compression test, but it didn't specify the RPMs while the test was taken, so they're kinda useless. They replaced the starter, they did all the flashes. Then they shut down and left town. I've been through 4 batteries. Multiple spark plug changes. 2 coil pack changes.
Anyways, just recently I replaced all the wires, upgraded coils to BHR, got a new battery, and put in new plugs ($700, battery alone is $200!). Still won't start hot. Well, it will, but I have to crank the **** out of it for 20-30 seconds as the RPMS slowly climb from 500-1000, and then it will catch. Starts up instantly while cold. So I have "gas station anxiety" because that's the only time this problem really occurs.
I'd love to sell this car, but can't in good conscious in its current state. Hell, my old post in the Sell forum is probably still up from 2018. I'll just keep driving it until it won't start ever again, then sell the MazdaSpeed bumper by itself. :-)

It's 99.99% bad compression imo.
Parasitic draws on 8s are battery killers if you don't drive regularly or use a battery tender.
Any weakness in a battery will manifest itself with bad compression.
I got $1500 on my '04 GT MT on a trade in with hot start issues.
What color is your bumper?
