I recently took a job as service manager at a Subaru store, and I am trying to help a customer.
He has an 05 WRX and put an 07 engine in it. There's a story behind it, but it seems mostly irrelevant, I think.
He had the harness done, installed everything and brought it to us to flash the ECU. There is no communication with the ECU. I guess the shop who did the harness is supposed to be pretty good, but I really don't know where to start.
Please forgive some of my ignorance, I'm still learning Subi-speak, but I've been working with cars for the last 15 years.
The car cranks, cooling fans come on, not sure if fuel pump is energizing. He has the ECU from the 07 and a new immobilizer. It has always been my understanding that lack of communication comes down to wiring, lack of power to ECU or a faulty ECU. Would the fuses and power distribution be from an 05 or 07?
The guy seems to have to have done a nice job on the install, I know he has some money wrapped up in this, and I would like to try to help him. This is not something we see everyday, and I'd like to get some ideas where to start. I don't want to see him have to spend anymore than he has too with me for this.
