Just watched a video on the C4-C7 feature called flood clear. You press the brake pedal and gas pedal all the way down then hit the start button. Your engine cranks without adding fuel so it clears it if its flooded. Then release the gas pedal and it starts right up. Also, a very good way to circulate oil after an oil change or winter slumber without damaging your engine. Maybe I'm just discovering something that everyone else already knew but being a newer C7 owner I found this feature to be helpful and wanted to pass it on.
Heres the video:
If the engine does not start and no DIC message is displayed, wait 15 seconds before trying again to let the cranking motor cool down. If the engine does not start after five to 10 seconds, especially in very cold weather (below −18 °C or 0 °F), it could be flooded with too much gasoline. Try pushing the accelerator pedal all the way to the floor while cranking for up to 15 seconds maximum. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the accelerator. If the vehicle starts briefly but then stops again, repeat these steps. This clears the extra gasoline from the engine.
I don't know anything about the brake pedal. My 16 manual doesn't mention it. Never heard of that for any car either but I could be wrong.
Interesting, but, the C4 does not have a start button
Mine did. The PO tried to sell it as a "security feature". What happened was that the relay melted and rather than to do it right with cutting it all off, soldering in a new holder and all that, he decided to drill a hole and put a push button. So you turn the key to "run" and push the button so that if a thief comes, he won't know where it is, hence the "security feature". And if you believe that, I have a bridge to sell you.
IIRC, even back in the carb days, it was a "clear flood mode". It's been in every EFI car I owned. I quoted the manual above. It is even in my 2003 Seadoo GTX Supercharged where that is how you fog the cylinders. I don't know why you have to press the brake pedal. Nothing said about that in the manual
Flood Mode discovered after I got tired of pulling the pump relay in my 2011 GS. 6 spd. Do you have to depress the brake pedal? It appears that I lost the Flood Mode function. Is there a fix?

A direct quote from my manual. Check your own manual online since you mentioned a C6
Ive been here for a while and never heard of this. Interesting. Not sure you can flood a C7 but I may be wrong.
If your meth pump goes crazy & pump that **** & it get a ton on the plugs this c7 is not going to start. But per say I can see this car doing it unless a inj r so keeps pumping gas in on the plugs. But that is why now plugs can go 100,k miles... Robert
I use this feature when I start the car for the first time in the Spring. However I don’t remember putting my foot on the brake. Maybe I do and just don’t remember it. OPS. (Old People ****).
My engine always starts. The question was about the loss of the Flood Mode function, which I use to prevent dry starts after car sits for a month. I definetly lost this function.
I know, old thread, but I was always. a big proponent of using Flood clear mode when starting my c6z that sits for long periods of time between being driven. It has always worked flawlessly. Yesterday however, the car started and revved to redline. The exact opposite of what I wanted.
so now I'm gun shy. Not sure how or why it happened -- but its really bothering me -- felt like abuse,
I didn't think it was supposed to start at all with throttle input. My foot was to the floor.
