I took a pic of a micra fuse panel (caution: it's a '93 micra so may be differnt one in yours.). This fuse block is to the right of the steering wheel ie INSIDE the car - there's panel - pull it off to see the fuses. I'll go an up load the pic and post the address here in a few mins...
From: Tiit_Helimut on 8 Feb 2007 15:37 Thanks for getting back to me. I found the fusebox inside the car and found a diagram on the back of the cover. The fusebox I have is a different layout, it has 7 rows of 5 fuses, but it showed me which the fuel pump was. I removed the fuse and floored the accelerator, whilst cranking the engine, repeated several times, put the fuse back in, and the car started first time (as if it had never had a problem!) I know how to avoid this again thanks to you advice, but how did this method work, and why wouldn't the car start in the first place (why is flooding a problem)? Thanks for your time, and sorry for the endless questions!

Thanks for your time, and sorry for the endless > questions! Many modern Fuel injected engines suffer from overfuelling / flooding if started from cold and then immediately shut off (or stalled), as for some reason the ECU's programming is such that it injects waaay more fuel than is actually needed for a cold-restart, and consequently there is too much fuel to ignite. There are at least a large handful of cars which are guarrenteed to flood if shut off after a cold start, and the K11 micra is one of them. If you are prepared, you can often effect a restart with a wide open throttle and a long crank, but only if done immediately. If that fails you'll need remove the pump fuse and / or plugs to dry them off. If it happens again, you know what to do now! Tim...

Thanks for your time, and sorry for the endless > questions! > > OK, here you go: Flooding, if you haven't already realised, is a condition where there is too much neat petrol and not enough air in the engine's cylinders for combustion to occur, hence the engine won't start. It happens because when the engine is cold, a higher amount of fuel is injected to allow it to run smoothly. Once warmed up, the fuelling is reduced considerably. If the engine is cut off abruptly during this cold period, e.g. if you stall or move it then switch off abruptly, a large amount of fuel gets injected without getting burnt, hence it lies dormant in the cylinders and causes flooding. Once in the flooded condition, you cannot get rid of the excess fuel and restart, because more fuel is being added as fast as you can displace it. This is where disabling the fuel pump comes in. It allows you to stop more fuel going in until you've cranked the engine enough to get rid of the excess. Holding down the accelerator helps because it admits more air into the cylinders, thus getting rid of the excess petrol quicker. Once this is done you can replace the fuse and all should be normal again. To prevent this happening again, you simply need to remember to leave the accelerator alone for several seconds before switching off a cold engine, and try not to stall! If you're not confident that you won't stall, run the engine for a few minutes to warm it slightly before setting off (you don't have to warm it fully). That should do enough to stop it from flooding.

Thanks very much for the help and advice everyone! I'll remember what you said, and I've booked myself into a basic car maintenance course, which I definitely need! Thanks again! |
