Introduction as new member/question about my endeavor
 

Hi everybody there, I am a new member in this forum, I have been reading threads from this forum just as a visitor and was helped, now as a member I want to present a problem with my 2004 mitsubishi endeavor. The car was misfiring on cylinder 6 swapping spark plugs, coils and injectors was not shifting the misfiring, I concluded that the ecu was the problem since the wiring to the coil and injector was ok. I bought an other ecu of the same number on ebay, it came not programmed, I thought that by swapping ic37 on the ecu board which is the eeprom 24c04 the immobilizer issue will be solved to allow the car to start with the new ecu, but no it was just cranking no start. I decided to reverse things back to the way they were before swapping, things worsened, the car could not start with any of the ecu. I don't know what to do now, Will anyone help?
Thanks.
