Question Start but won't Idle

Searched. Prolly need to do more searching...

On going build, T2 JDM Motor, 75,XXX Miles, Sitting for 6-8 Months.
Motor is in the Car with NA tranny. Spark is good, Plugs are Good, Oil is in... The motor holds compression, just no number as of yet.

We tried to start the motor 2 days ago, It started. Would not hold revs, we had to hold the throttle open or it would die. It revved up to 3-4k at max, wouldnt go any more than that. As soon as it started, there was a lot of white/blueish smoke(was losing sunlight so we couldnt really tell...). Also there was a whole mess of dark goop/oil and water that came out of the exhaust, mind you I only have a DP on. Yesterday, we tried to start it again and It didnt want to start... We tried to clean the motor out by firing it w/o plugs, Theres a gang of gunk and gas when we turn it... And sometimes no gas, which either meant, no gas(Filled it with 91+Octane booster[3 gals].) or my injectors are ******* up. Also came to the conclusion that the injectors are only HALF working, once we tap the injectors gas starts flowing through again... But it goes out again after a couple of tries...

My question is... Are my injectors fucked up? Can I use my NA injectors for my T2? Does the water mixed with the gunk that came out of my exhaust mean that my water seals are blown? Does that mean I have to rebuild this ****?!?!?! DAMN! Is it possible that the turbo is shooting oil through the engine it self? Or I mean, is that where the water/oil mix from the exhaust is coming from?

I really just want extra input... I tend to confuse myself. I'm going to try to start it again today... I Will post picture when I can.

Thanks for the help![In Advance]
Lyle

it could be an afm problem. try swapping it out with another t2 afm. also check if the tps is still in workin order. the smoke could just be from it not having been started in a long time n just needs to be run for a while.
