1999 celica gt (st204) w/3sge gen 3 swap wont start Options

[ink_eyes_25]

Im doing a jdm 3sge gen 3 swap and the darn thing wont even try to crank like the battery is dead. I know im getting power b/c theres a fully charged battery in it plus all lights works ect. Basically i try to turn it over and it doesnt even crank, no response just silent. Any idea everyone? Heres a list of things i swapped in:

-JDM GEN 3 3SGE ENGINE (non beams, just the regular one) + TRANNY
-JDM COMPLETE ENGINE HARNESS (WITH THE FUSE BOX ATTACHED)
-3SGE GEN 3 ECU part numer: 89661-2D490
-ORIGINAL IGNITION LOCK CYLINDER W/ OEM KEY (alarm control built into key)

Note: key, lock cylinder, and ecu came from the same donor Celica located in Unitied Kingdoms (most likely EUR spec st202). Also note that Im using my stock body harness in my 99' celica is a USDM spec st204.

I havent installed the new lock cylinder yet, but will try to soon. Does it really matter that im using EUR spec 3sge ecu on a JDM 3sge and JDM engine harness? Could it be that the ecu i ordered has a immobilizer programmed on it and car isnt responding because im not using the key that came with ecu? And also maybe the pin outs on the ecu dont match up with the engine harness? Well i appreciate any help from anyone who did this swap or have alot of knowledge on these swap, thanks a whole lot in advance!

got your pm, but thought it might be better replying here

UK spec are a bit special as they sometimes differ from our JDM spec ST202, from what I understand the UK owners have a factory immobiliser. Haven't come across a JDM one that has.
the ecu part number you gave SHOULD work.

first thing to do is to check all connections are correctly connected, pushed in the whole way, earth grounds off the motor & trans. as your not even cranking yet.



also I'm pretty sure the white little box with little ball point button you were talking about is the door alarm

Yeah I kinda figured that it was the door alarm, idk why he sent one with the ecu lol. I'm 100% sure I got all the grounds but ima double check those connections this weekend. Also kevinpetch say its the jdm harness having different pin outs than the EUR spec ecu. Can you confirm this? I would hate to try to locate another 3sge ecu ugh
