Hey guys new member I'm actually from Australia but decided to join here as well to get other opinions.

I've only had my RX8 about a month or so, in this time I've been doing a lot to clean it up. Oil & filter, plugs, leads, coils, fuel cleaner etc.

Ever since I replaced the plugs, leads and coils however I've been having issues with Hot starts. I've researched this problem and it doesn't look good Some say run through a pre-mix something I'm currently doing, some say its the starter motor, worse case it's compression.

However in the two instances I've had over the last few weeks where I tried to start it while warm and it wouldn't start, engine deflooding procedures have worked to fix the issue.

The first time I left it for a bit and tried again after removing the fuel pump fuse. It almost started but then obviously ran out of fuel. It felt that I almost didn't need to do the fuse trick.

The 2nd time today was after getting fuel. Now I had just put in premix of oil so this could have caused issues but holding my foot on the accelerator to deflood worked fine and the car started on the 1st attempt afterwards albeit a little slow.

I've looked at a number of threads and I thought I'd still ask because I'm worried that this could be a compression issue but I'm a little confused why defrauding would help it start?

Hi, did you read the "Hot Start and Flooding Issue" thread?
Idk how to post links from my phone.
I'm not an expert, but the only thing I can think of with bad compression related to flooding is that when it's hot, the loss of compression won't allow the fuel to ignite and by the time you go through the deflood, the engine has cooled off enough to start.

Get a rotary specific compression test at your local Mazda dealer. That's the only way you'll know for sure. I have one done annually just for peace of mind.
