help, engine injested some water now won't start

Ok (1/4 quart approx) into the intake, I am hooking up a water injection system and hooked it up wrong initially so it squirted water into the engine as soon as the key was on.

I have tried pulling out the plugs and cranking (twice), I have been cranking this thing for a long ******* time, I have tried starting fluid, it seems nothing will get this thing to start. I can turn injection on and off (haltech), and I can see (FP gauge) that the pump is working, and that the injectors are firing.

I have verified spark, everything is good, it even sat over night

Now what ???

WD 40?

My compression is good....

WD40 should work.

I don't know if you can use other products that displace water, like a penetrating lube, in a rotary.

I have an oldschool plug sandblaster, the plugs go back in looking new every time they come out.

I will try WD 40, afterall WD stands for water displacing.

one can of WD40 in and It seems to have improved, the compression strokes seem more labored as if more compression is present, still wont start, but I can hear it sort of firing...

Treat the engine as if it were flooded. Pull the plugs and pull the 30 amp EGI fuse under the hood. Accelerator to the floor and crank in 10 second bursts to spew any fluid out of the engine. Put an ounce of ATF in each lower spark plug hole replace the plugs and the EGI fuse and start it. The ATF will help the apex seals seal for the compression stroke.

The ATF trick finds its way into every thread, it seems. :P I'd say keep up with the 40, since you're already finding an improvement.

WD40 worked eventually, I needed to pull the plugs to evacuate water 2 more times.

Now it runs great again.

By the way water flooding is much worst than fuel flooding, water has the effect of making the spark plugs do nothing.

i use tranny fluid for carbon and that might work for water. you might want to try some methelalcohol or maybe some wd40 but more than likely what will happen no matter what you is detonation due to adding another flameable liquid into your motor. i had a really bad expensive water **** up and it detonated on me when i went to get the water out. be careful that the insid eof your motor doesnt get rusty or you will nic up your apev seals and shiz real bad.

you could also try some fogging spray or throttle body cleaner (not carb cleaner).

Yeah, the water is a PITA to evacuate. Glad you got it running again.

There's no reason to use ATF. Just use regular old oil.

I agree, your normal engine oil works fine - why further contaminate your engine with something that shouldn't be there?
