Theres 10,000,000 threads like this I am sure, but for my 2 cents, I did nothing to the car to make this happen. The most recent work I did was a massive vacuum hose job this past summer and the cars been running great for the past 5 months.

During that massive job I did check the coil packs and everything tested fine, and they all had proper, resistance, and new spark plugs and wires were installed. Fuel injectors were cleaned flow tested and balanced at the same time.

Besides possible low engine compression, does anybody have any other ideas?

How many miles on the plugs? It's possible that it's flooded.

I agree...fresh plugs never hurt no engine

The plugs probably have about 2-3K miles on them, I replaced them this year in june I believe. I never thought about the possibility of it being flooded? Thanks I look up some threads on that

I performed the deflooding method just now, and after several attempts, finally it barley started up with a lot of white smoke coming from the exhaust apparently from the excess fuel. After it warmed up, the smoke cleared up and I turned it off, and tried starting it again several times, and it starts up fine everytime as if nothing ever happened. Guess you guys were right, saved me a big headache.

This has never happened to me before in the past 3 1/2 years Ive owned it so it freaked me out. The real test is how it behaves tommorow and over the next few days, I think its ok now. This fuel kill switch really payed off!!!

See if the fuse to your Fuel Pump is A) good and B) snug. On my car, the previous owner had a bunch of gauges tapped into the Fuel Pump fuse and all the wires around it loosened the 'female' side of the fuse once removed.

I had an identical problem then found out although the fuse was fine, the connection was bad, thus causing the issue. Tightened it up and I was good to go.

On the same vein, you might want to make sure your fuel pump didn't go bad (that was my first instinct on my issues).

A mate of mine is a mechanic at a Mazda dealer in Iceland. I had this problem a few times when I lived there, he told me that a good way to avoid it is when you are about to turn the engine off, slowly build the revs up to 4000-5000 and then kill it. The engine running down uses the unburned fuel.

Of course it doesn't work if you have a turbo timer

Exact same thing was suggested to me by an RX-8 owner

My mate said it's actually in the RX-8 owner's manual, but that no-one ever reads it.

Started the car again today and everything is fine now. From now on when im moving the car a very short distance with the engine not fully warmed up, im gonna turn off the fuel pump with my kill switch with the engine running, that way the engine dies from fuel starvation, and by the time it dies, there will be no more fuel left over for it to flood (read this from another thread) Thanks guys
