Default How do you unflood a motor?

I just recently finished up my diesel turbo motor, and I have 1000cc injectors being controlled by utec, welll I had to get oil to the turbo so I disconnected the crank and cam sensor and cranked motor over. Well, ofcourse I flooded the motor, how do you unflood it? OR should I just go with new plugs. And dont worry once the car is up and running I will be having pics and everything else.

The quick way...



Doesnt leave much though....

Usually when a motor is flooded, you simply floor it with no electronics/whatever hooked up to give more fuel (floored to allow maximum air flow) and turn it over for a few minutes giving it time to rest....

Then try it normal...

Good luck.

Pull the plugs and manually crank over the motor. Or disconnect the fuel pump's power, pull the plugs and crank. Afterwards, when you start the car, just put a video camera 10ft behind the car and post up the results.

Next time pull the ECU and then crank.. this will allow the car to crank with all sensors plugged in, and not inject fuel or spark.

Simply pulling the plugs and crank the engine over by hand, once most of the fuel is out you can crank the engine over with the starter (the way I mentioned above) will de-flood your engine.
You want to get the fuel out and not let it sit inside the cylinders and seep into your oil.

Maybe I'm missing something, but if you disconnect the crank and cam sensors, the computer wouldn't be injecting any fuel either.

i have *never* had a problem with flooding when I'd crank with the crank position sensor disconnected on any car, Subaru or not.

You can simply pop out the ignition fuse.

Or hold the pedal wide open. This shuts the injectors off at crank but leaves the ignition going. Should clear up the fuel.
