So without going into detail about why or who made installation errors (me...) I was swapping tunes from the 3 bar to the 2 bar to trouble shoot my meth system, and without realizing it my pump was spraying full blast while the tune was loading.. Im thinking the computer was giving false info causing the 2 bar sensor to see boost.. Long story short, filled three of my cylinders with meth/water and the car wouldnt start.. just acted like the battery was dead when I hit the start button.
So, I pulled all 6 plugs, turned the engine over and got three big gushes of stuff out of the engine. Just wondering what the popular opinion is on if I have a bent rod or three, or other issues? I plan on letting the spark plugs stay out for a couple hours, then putting them back in and starting it. Tomorrow it will get a fresh oil change (if it is alive that is)
To be clear, I didn't realize the pump was spraying and filled a couple cylinders until after i tried to start the car.
I'm curious to this fix myself. OP I hope you sort it out quick, and that no damage was caused.
Did you hear it turn over at all? Or was it slow when trying to crank? If it didn't crank at all, you might be safe...
I hope your motor is ok.
Maybe this should serve as a warning for everyone to disconnect their meth when flashing since it seems all have some sort of weird behavior when doing so. And obviously some things may be going on that can't be seen....
Oh damn...thanks for making up my mind on meth..i never thought of that happeneing...i think my wife would seriously try to beat me up if i needed a motor for the daily driver that would crush the bank account.
Hope its ok
By no means am I a mechanic but if the engine did not fire or role over how could anything could be damaged/bent? I would think by drying everything out and installing the plugs it should start. Just my two cents...,.

Make sure the meth kit is disconnected and will not spray.
DO NOT try to start the engine until you have dried out each cylinder thoroughly (visual verification/boroscope). Compressed air will help. Crank a few times without the plugs installed and the fuel pump fuse pulled.
DO change the oil BEFORE trying to start the engine. Check the intercooler, empty if necessary.
Once verified, install plugs & reinstall fuel pump fuse. Leave the meth kit alone for now. Load a non-meth tune and try to start the engine. If that is OK, drive around for a while before trying to proceed further with the meth kit install/troubleshooting.
My 2 cents. Good luck!
Just emptied almost a gallon of liquid from the CAC... Jacked up the driver side and used an oil extractor meant for a boat (also used this to vac out the transfer unit, works amazingly well) and had no issue getting at all of the fluid. Also removed all of the plugs and spun the engine over a couple dozen times, the first revolution there were a couple "explosions" of liquid being ejected from at least one of the cylinders. The oil will get changed in the morning before I drive it.
Other than obvious engine sounds, what should I be keen to look for when starting it for the first time tomorrow?
How long would you say that meth mix was in those cyclinders? As SHOdded said, change your oil just in case any of it ran past the cylinder rings. You do not want water or fuel in the oil at all. You will burn up bearings. Since engine did not fire, I doubt the starter has enough torque to bend a rod. Glad you caught it. I hydrolocked my mower the other day due to a stuck fuel valve and emptied the entire fuel tank down the cyclinders and a mower mechanic told me the same thing SHOdded said.

Unfortunatly I had to leave for Ft Campbell for a Flight Simulator period, so it was sitting in the cylinders from about 11am to around 9 pm.. To top off the night, the car is half way in and half way out of the garage... so I can't close the door :(
Im getting anxious to start it up, but now I am also suffering from a dead battery.. So unless the trickle charger works its magic overnight, I will be exchanging a nearly new battery in the morning at auto zone.
Best of luck on the flood recovery

SHE'S ALIVE!!! After a night with the plugs out, an oil change and sucking a scary amount of fluid from the CAC (at least it should be clean now, right!) she is idling with a fair amount of consistency in the driveway as I type :) There was lots of condensation on the inside of the oil fill cap, so I'll keep an eye on the condition and change it in about 500 miles again just to be on the safe side.
Huge thanks to the members here for advice and to Julio @ Alkycontrol for the countless emails helping trouble shoot this problem!
Did they figure out exactly what happened or is it just one of the random "tuning gremlins" that occurs during the flash process?
UGH that s*** is scary. I'm happy she's alive.
You should be fine, this exact something happened to me a couple years ago. Always change your MAP sensor 1st, or pull the fuse on your meth system.
I just had this happen while tuning my 93 mustang... 1 of my injectors was dumping fuel that bad it was coming out the tailpipe. I pulled plugs and emptied out the motor, put old injectors back in.. Running great again... But it is not a good feeling when you crank the motor and it stops dead...

What meth system are you running? What is your quickest way to disable? Just pull the main power to your pump?? I'm new to all this stuff...
thanks in advance!!

This is a 5 year old thread, so I doubt the guys are gonna respond unfortunately. I would start a new one if you have questions about methanol.. But to answer your question most of the meth controller have an off switch. Worst case if you pull the plugs out and suck out the meth from the cylinders and then change your oil immediately.
Back in 2015 the two biggest kits were the Snow Performance kits where are not rated for 100% methanol and then Alky Control Kits from Julio which are rated for 100% methanol.
