They all do that, it's the way the computer works. You simply cannot move it from inside your garage to outside your garage for a wash without turning it off. The only way round it is to restart it with your foot on the floor on the accelerator and wait for it to catch. But before you do that, wait for ten minutes. It is not a fault, per se, it is just the way those cars are.

unfortunately its a fault with the micras, its being flooded, they don't like going a short distance stopped & then re-started. ive come across a few of these that do exactly what your describing, I usually remove the fuel pump fuse spin it over a few times & refit the fuse, starts fine then. your best bet is to keep it ticking over if you move it a short distance before turning it off. as far as im aware there's no known cure.

Common fault with these engines. Basically when you start it, run it for a while and turn it off, the engine gets flooded with petrol. Only solution is to remove the fuel pump fuse and crank for about 10-15 seconds. This will disperse the fuel that's lying in the cylinders. Replace fuse, and try again.

The only *real* solution is not to drive the car for very short distances. The above is a testament as to why not.

This seems to be a fairly common 'fault' with later engines. Not confined just to Micras. I had the same thing happen with my 525i BMW. Seems the only answer is to floor the accelerator, and keep trying with the starter until it starts or possibly flattens the battery. Took over 15 mins of trying before my BM fired up. Mike.

This is **NOT** a fault in any way- it's a result of the way nissan programmed the ECUs fuelling maps.

ALL the bubble shape Micra's will exhibit this flooding symptom when started from cold and then swtiched off without being warmed up.

Alot of other fuel injected cars do the same, I could name a dozen or so.

Ensure you let it at least partially warm up before switching off, and you will not have the problem.

Tim..

I wonder if those Bosch multi-electrode spark plugs would improve things? Presumably the plugs are soaked in petrol and are shorting out through the liquid. With more heat in the block this would dry off (My Nissan 2.0i also has this problem to a lesser extent)

A moment for some well-aimed car-abuse, I think.

Thanks for your time to write in, to help me out with this situation. I guess i will have to make sure the car is always warm before turning it off, which is a annoying fault. Thanks again Karim

Not the only way. If you have a 'boot only' - don't know what these are called - key without a transponder, then this will turn the engine over, without activating the injectors. This rapidly clears (IME) any remaining fuel.

Also, turning the engine off, while it's revved to 3000RPM or so should also help, when it's parked after a very short time, as the engine pumps more air through while slowing down, removing the remaining fuel.
