I never turn my engine off at petrol stations!

I usually leave the engine running so you can see where abouts the needle has moved to as I'm one of those anal people who drive around with only up to half a tank to save weight 
Seriously? You don't just get it so it's "about full" you actually fill it until it's EXACTLY half full? You do know you probable waste more than you save with the extra trips to the fuel station and the time time sitting their idling away pointlessly?Also, if you left the ignition on position II but the engine off you might get the same effect?

Healthy rotaries should start fine from hot or cold. Get it compression tested, if that's good, change the starter motor. My understanding on the mobile phone issue was that it caused interference with some of the old flow measurement systems in the pumps - i.e. using your mobile could mean that you were charged for more/less petrol than was supplied. I didn't think it was anything to do with the phones themselves - presumably if it was, then you'd be asked to switch your phone off completely before entering the forecourt (rather than just not using it). Or for that matter, before driving anywhere!

Can't remember where I saw/read it, but independent testing under any circumstances, even tampering with the phone couldn't get any sort of spark from it, certainly couldn't ignite fumes in perfect for ignition conditions.
I saw it on Mythbusters, but could also have been done elsewhere.OP are you sure it's not just the flooding issue that RX-8's can get? I had a 2006 RX-8 and never had the hot start issue, managed to flood it a few times moving it out the way of delivery vans / neighbours.

Right, a few facts:
1. Healthy rotaries start fine when warm.
2. Healthy rotaries start fine when cold.
3. Healthy rotaries have issues starting when you run them for about 30s then turn them off: that's when they flood, that's when you get restart problems.
4. A rotary not starting when hot is a symptom of low compression.
5. A more powerful starter motor will help with this, but you're just masking the problem. It won't help for long.
6. A compression test would likely reveal figures in the 5's for your engine.
7. Your engine needs a rebuild.
This. When you test drive an RX-8, get the engine warm and then turn it off for a couple of minutes and try restarting it. If it doesn't start immediately, walk away or factor a rebuild into your price.1. Healthy rotaries start fine when warm.
2. Healthy rotaries start fine when cold.

ks to be honestThat's the only time I can think of a new RX8/new engine failing to start, with the exception of fault somewhere else.

Bullst, my RX-8 is an early 2004 model with the original starter motor, i.e. low rpm one. And I got my starter price figure from the most well respected rotary parts website Mazda Rotary Parts:
Genuine Faster Starter - £408: http://www.mazdarotaryparts.com/bgenuine-mazda-rx-...
Compatible Mitsubishi Faster Starter - £276: http://www.mazdarotaryparts.com/bmazda-rx-8-r3--mi...
So, the £300 isn't the exact number but it is in between the two. Anyway, you aren't wrong that several early RX-8's had faster starter motors fitted to them over time but not all of them did, like mine. Which reminds me, I should put an uprated starter on mine as a form of insurance.
Yes I said early RX8's have the old starter the 1.3kw one. I have a January 2004 RX8 with this starter. I'm saying that all models with this particular starter do not start when the engine is hot. Does yours? If it has the original starter, it will not start when hot.t, my RX-8 is an early 2004 model with the original starter motor, i.e. low rpm one.

Also you might want to shop around if you're looking for a starter motor:

£92 on ebay mate. Sod that £408 lark.
I'm afraid you've been misinformed.
The more powerful starter was introduced to try and help with engines that had been flooded, not to solve the made up hot start issue.
Healthy early rx8s have no issue starting hot. That's nonsense. Your car may be 'excellent condition', however, the engine is tired. 60k, although not a hard and fast rule, is classic 'low compression' mileage. Get it on a proper rotary comp tester. I'd wager money on it being very low 6s or in the 5s.

I hired a Caterham last month from Caledionian Classic and the battery was knackered so every time we switched the car off it needed a bump.
I tried this at every station we stopped at on day 1 and all would not start the pump until the car was off. Was quite annoying as we wanted to save the embarrassment and fuss of having enough room to get the car going.
Maybe larger forecourts would be easier to manage this as they are inside shops with doors and double glazing. Was also annoying as some of the stations had actually sold out of petrol which meant we didn't ever want to let the tank drop much below a third remaining. Still managed the 800 miles in 2 days but had a lot of abuse of the owner since we were late back with the car.

Nonsense, I'm afraid. Mazda dealers started fitting the uprated starter when cars with failing compression started to show signs of poor warm starting. It was a temporary fix at best. V8RX7 said:
Your engine is approx 6' from the filler, if you open the bonnet can you see a load of sparks - no.
Cars driving up to the pump opposite are running and possibly closer than 6' - so how dangerous is it ?
It's not.
My fuel filler is only about 6" from my engine (MR2 MK1 SC to save looking it up) and now I am worried I will be engulfed in a ball of flame if I try and fill up when I have had a little drive.Cars driving up to the pump opposite are running and possibly closer than 6' - so how dangerous is it ?
It's not.
In Italy they smoke while filling up. I have been in a car where the attendant was filling up and had a fag hanging out his mouth. The one near Naples used to regularly do this although not seen it for two years now. The one in the village down the amalfi coast were still smoking last year.

Mine didn't on 80k...I think you have an engine rebuild looming, new starter and magnecore HT leads may see you through a bit more but if you have serious hot start problems already I think you know what's coming.
