If it smells of fuel it might just be flooded.

Could be worth while giving it a tow start? The tow ring screws into the front bumper if you haven\'t used it before, took me ages to find that when i towed one in the dark :rollin. It\'ll take a fair distance to start but hopefully it\'ll be fine for you!

First of all, welcome,

Yes it\'s flooded i\'m afraid.

There are various de-flood procedures but as Dave says, a tow will start it if your confident you can do this.

If try this simple way,

Make sure you have a well charged battery, remove the fuel pump fuse located in the box to the right of the air filter.

Get somebody to turn the car over and after 2 or 3 minutes put the fuse back in while the engine is still turning over and it may well start.


One big tip once it has started is, don\'t rev the car thinking a good rev will clear it.

Let the car warm up naturally using as few revs as possible to keep it running because all a good rev will do is ignite all the fuel laying in the catalytic converter which will potentially burn it out.

If there are big white spots then they need changing the wife\'s 8 had light grey spots on the bottom and the starting was like a flooded piston thing lol. Changed the coils new plugs and new battery never had a problem since.

Hope this helps

Don\'t forget to pin the throttle open when you take the EGI fuse out, it will allow for fresh air to be sucked into the engine clearing out the richness.

Mazda rotary parts also do some shiny shiny new coils :D
