Flooded engine (broken down)
So I broke down the other day, first time I have ever done so in the middle of a busy road.
Pulling out onto a main road, I saw a gap so gave it a bit of throttle, but then decided the gap was too small so I hit the brake. But the engine then died and wouldn't re-start. Luckily I was close to a garage so with their help I was pushed to there. Was told the engine was flooded and the plugs had to be removed and dried out. Is this likely to be a one off incident, because I accelerated and backed off quick, or is there likely to be a bigger problem somewhere? Note mine is an auto not a manual. Cheers. |
This sounds a bit strange to me, I don't think an engine can be flooded while it's running, trying to restart it could flood it.
A lot of questions... Did the garage remove the plugs? Were they wet with petrol? Did it restart after? |
I agree with 'volvo again'. The most common cause of 'flooding' is continual cranking without the engine firing, more usual in my experience with carburettor fed engines - I don't think I've ever had a FI one flood on me.

"Flooded " ! more likely a wiring connection seperated when you braked suddenly . Before removing any parts / throwing money / having a hissy fit , my first port of call would be to plugin & read / delete any codes stored in the ECU .
If you have any code/s you will be a lot closer to a remedy , rather than groping in the dark for answers . Modern engines are nothing like as easy to fault find & rectify purely because of all the magic goblins under the bonnet working their magic ( or not ) |
Faulty coolant sensor could cause over fueling and poor starting issues that you describe.

thanks all, I will check the fault codes, although I think my reader is OBD2.
I'm pretty certain it was an over fueling issue, so maybe I need to do some searching as to the cause. It did happen 8 months ago in a car park, and after I left it half an hour it started. It was a similar problem. I wonder how the coolant sensor could cause over fueling? cheers all |

Coolant temp sensor provides the ecu with temp data to allow the fueling to be richened in cold temps to assist starting/running. If it’s feeding duff data then the engine will be running extremely rich, causing bore wash, plug fouling etc. |

Could it be a failing crank position sensor?This would allow the engine to turn over but not start which might give the symptoms of a flooded engine?
