JDM T2 Swap, Wont start!!!

Okay, I just finished up my gxl to t2 swap and I turned the motor over and it fires off and feels like it wants to start like crazy, it burns clean white smoke coming from the downpipe and everything...There are a few spots around the intake and intake manifold where theres no hoses and holes...can someone please send me some pics of the passanger side of the motor, around the intake manifold and intake, i need to see the hose set up...I think its a vacuum leak or somthing...I cant wait to drive it haha =) im sure its just somthing minor with the motor.

Did you check for spark?

Did you check for fuel pressure? (I assume it has it due to the smoke, but you never can tell)

You also didn't specify S4 or S5.

yes, it is a S5 it does have compression, there is a radiator sensor not hooked up, and I do not know where the wire/connector is to hook it up, and reading in the manual it has to read 6 diff. sensors to crank and run the motor, im guessing this sensor (radiator/water temp sensor). Also there is a hole in my intercooler up-pipe, also, there is a hose broke off that is suppose to run into my blow off valve, I'm thinking i need a new blow off valve kit, new up-pipe and ill see where it goes from there, if that dosnt work, ill spray some gas into the intake to see if it fires up, there might be a bad sensor not letting my injectors open up...Could be alot of reasons, but the motor wants to turn over but somthings just not letting it, the compression sounds very well, so im not sure, there is a port where a hose gos ontop of my intake manifold and I dont know where it is suppose to run to...its so confussing haha...

I would take a few pics of mine to show you, but I'm not running any emissions, so that may throw you off.

The sensor on top the radiator is for coolant level, doesn't affect the engine starting or running, but it does make a rather annoying buzzer go off constantly. (As we all should know.)

All the cracked pipes and broken hoses you describe are after the AFM, so that is a pretty bad leak.

Let me know if you want pics, soon. I am taking the turbo off like Wednesday, so all that crap will be off for a while.

yes, any pics would give me a better idea of what im looking at. And the sensor im talking about is on the bottom right of the radiator...the coolant sensor is hooked up. but yeah, haha, I mean, all those holes and cracks around the intake area could be preaty bad hah.
