svt idling n running problem,please help!

[cuscostrutbrace]

i have recently transplanted svt into ke70,engine wiring complete,but no dashboard wiring
since the engine does not come from halfcut..i got 2 problems

1.cooling system:i have closed the original water inlet and outlet at the head and make a new pipe outlet at cylinder no 1..and the inlet at the back of the water pump,the suprising thing is,when i pour water into the radiator,it doesnt come out at the outlet at cylinder no 1,but radiator appears to be full,so i try pour water at the outlet pipe first instead,it also doesnt come out at the water pump..i have checked the pump,all in perfect condition..then i shoot air using the airgun at the water pump inlet at the block,i can feel no air at the head outlet..strange!...it's like the head and the block are seperated by a plate.

2.the engine cant idle,the airflow sensor flap doesnt even seems to be sucked in to its idling position,and the engine cant maintain rev...it only can be revved,and must constantly being revved,or it will die.i have monitored the AFM action,when i crack open the throttle,it does suck the flap,but when i hold the throttle at certain point,the AFM slowly closes,causing the engine to die,unless if i hold the AFM open with my finger,then the engine can maintain rpm.it's like the engine cannot hold vacuum at part throttle..i am certain i have closed all hoses and no vacuum leak at the intake
then i try plug out the AFM socket and remove the AFM completely,the engine can idle,at 800rpm,but revving very sluggish and backfires through the intake,and it cannot rev pass 4k rpm but it can hold rpm though...

the ecu seems fine,AFM voltage fine,TPS voltage fine,cam timing fine,ignition not yet to be checked but the engine have been transplanted as if,no fiddling with all those thing

PLEASE HELP...i need the car to be finished by the end of this month...my classes gonna start next month

Hi

You are not suppose to close the old inlet and outlet. Instead you are suppose to LOOP the old outlet BACK INTO the old inlet.

When you simply close them obviously the water is not continuously connected within the passage anymore.

I still think your ECU is dead or ISCV leak

owh really,silly me...but one of my frend did just that,and it does'nt cause any problem,but i didnt know if he changed the head gasket to 16v gasket,i'll check with him and post later...

even if your friend used a 16v gasket he'll still need to loop it, else he need to drill into the head to force a by-pass.

Theory says "loop". There's 3 ways you can do it.
