Default D16 turbo runs really rough

I recently boosted my d16y8 and long story short i mixed up a couple lines and ended up getting what seems to be water/coolant on top of piston 1 and 2. I checked the compression on all the cylinders and they were fine and also checked the cooling system to make sure it holds pressure and it does. We got most of the liquid out by just running it. We kept running it and pulled the spark plugs to check if it burned out and it did. Now it seems like all the cylinders are getting a little moisture in it and also the throttle body seemed to have some moisture in it as well. Now it doesn't want to start but cranks over all day long. What could the problem be?

Perhaps you because lubed your cylinder walls with coolant? Do a compression check.

Fuel
Spark
Compression
Timing

If all those are there, then motor motor should at least run, perhaps rough, but it should run.

What have you verified of those 4?

What lines did you mix up to get coolant on your pistons? Sounds like a lifted head or something. I don't know if any lines that feed right into the piston unless you're feeding it into the intake or something...

It was a coolant and evap line that got mixed up. I have all of those 4 but the only one that it could be is maybe spark because every time after running it they get a little wet.

If coolant and evap line got mixed up...my question is, did you drain your oil and coolant and refill them?

Yes the fluids are fine. When I start it up the boost gauge reads -10 and AF gauge stays at 10. Car blows out smoke (mix of white and black smoke). I pulled the plugs again and they are all a little black but cylinder 2 blows out a little bit of smoke. I've been looking it up and it's seem it could maybe be the FPR. I can't seem to find any boost leaks so I don't know why it's only at -10 vacuum. I have a base map tune on the ecu right now.
