OK, I have heard everywhere that when someones FC floods, they have to open the hood remove the egi fuse, crank put it back in and crank again. I just pop off a relay thats below the steering column and turn the engine until its about to start, the pop it back on, seems easier to me than to have to get out of the car.

Under the steering column? Where? What does it look like?

Its a yellow relay to the right of the steering column, under the dash...

And this isnt a new trick...

I had the entire interior (including dash) out for restoration, so I put a switch in the indent above the hood release.
I just reach under and flip the switch, crank for a bit, flip the switch again and startup.
Also, should reduce possibility of theft.
I've got lots of pix if anyone's interested on how this went in.

The easiest and quickest procedure for me was just to crimp the fuel "in" line to the motor. I've only flooded 2-3 times in the past few years but I've always made sure to have a vice in the car. Just be sure to wrap the teeth of the vice with tape so it won't tear the fuel line. Sure, it's ghetto but it works...crimp the line and the car will start then stall (when starved of fuel). Remove the crimp and it starts right up

WTF?

Why not just pull the EGI fuse or put in a fuel cut switch?
I takes 1 second and you will do no harm to your fuel lines.

i had a fuel cut switch installed. Works every time. (it rarely floods though)

I knew of the EGI fuse trick but it didn't help me in the situation I was in 2.5 years ago. My coolant seals were leaking coolant into the combustion chamber and no amount of unflooding with that trick would work because the coolant would foul the plugs and it just wouldn't start.

I had to do the vice grip on the fuel line trick and have someone hold onto them while I cranked the motor. As it cranked and cranked eventually it would sputter and start and that is the point you take the vice grip off or else it will stall. I would floor the throttle for ~10 seconds and for 2 of those it wouldn't even rise above 1500 rpm and then it would slooooowly go up to redline, burning out all the fuel in there. It honestly felt like a 2nd or 3rd gear pull doing that.

I got the engine rebuilt though so now it is all good

Yeah, I guess that was major flooding, but for minor flooding, and for the guys like me, who.....even on a brand new rebuild, cannot get the car started back up again once its been started once (maybe product of the FCON) it saves alot of time to just pull the relay from under teh steering wheel, start it, and put it back on.

This is why some in this post are suggesting the operator disable the injectors so fuel is not released. Injectors won't open. The operator can crank all day to purge th rotors, and no fuel will be spit into the housings. This also avoids fatiguing the fuel line with dents and crimps, and enormous backpressure across either/or the fuel-pressure-regulator and pump depending where one crimps the line.

Well this is not new or anything, im sure you guys have heard of this before, but it worked for me. My car got flooded before and this is what me and my friend do. We push the car while the gear is on 2nd whithout pressing on the clutch. Offcourse you will step on the clutch so the person can at least get a boost to push and then let go of the clutch let it get some speed and it will more likely start ( Do not press the gas pedal and just have the key at "ON" positions only ) I hope this help

That yellow plug under the steering wheel is the fuel pump relay.
