Author Topic: Carb flooded. (Read 2151 times)

I have had my Honda Jazz for almost 2 years and it has started straight away every time.
When I turn the ignition I do not need to depress the accelerator.
Last Sunday I needed to check the mileage and did not realise it could be done without starting the engine. You live and learn.
I started the engine, looked a the mileage and turned it straight off.

On Monday I went to start the car to go to work and it would not start, I tried a few times until the battery was getting low, then called the breakdown company.

An engineer came out in about 1 hour and said it was flooded, kept trying to start it until the battery was almost flat, sprayed something into the air filter (high octane?) and used his portable battery pack, had another go and eventually it did start.

He said that if I had left it for half an hour it would probably have started, but I had left it for 1 hour.
I think (and am most probably wrong) that me starting it up and turning it off straight away on Sunday caused the problem, and it had not reset by Monday. I would be interested to hear your thoughts on that.

It has been fine since but I am a bit concerned that it could happen again and I won't be able to start it.

I'm far from an expert but I have never heard of a car with electronic fuel injection being 'flooded'.

It happened to me once
If it happens again
Push the accelerator to the floor and crank the engine until it starts
By pushing the accelerator to the floor the engine will run leaner, that is why it will eventually start

You've discovered the need to know about the "Clear flood mode". Plenty of references on this forum, try this:

Frankly, your breakdown man was a muppet not to know about this.

Thank-you for the helpful replies and the link.

So if it happens again, floor the throttle while cranking the engine.

My suspicion was correct about me causing the problem by starting the engine and turning it straight off again.
