Hi,last week i just collect p28-g01 ecu from junk yard for free and test it to my h22a, after i plug it at my car, car can crank, but i cant start, then after i check engine was flooded with fuel. It got no spark at all spark plug but injector work,

So i check distribute with test lamp and got all light on sequence. At last i try to change the ecu with old one and car running back to normal.

It is possible any circuitry in ecu damage and not given any spark to all spark plug?

 

possibly as long as the all of the conectors match up you should be fine. open the case and look for any burns its only 5 screws.
