In need of advice

[Cruzer2]

Hello everyone I'm cruzer from Guam

I just got a used engine control unit (computer) via ebay.  It comes with a warranty and exchange or refund option.

I installed the unit the engine turns over but the engine doesn't start. 

Any suggestions please?

I would imagine it is coded to the car...you either need to get it coded to yours or you would need the immobiliser system to match the ECU
