Hello everyone, ive tried another ecu and it still does not communicate.
Ive replaced

Ecu
Battery ground
Main relays
Fuses
Checked power and ground to ecu.

Lost communication to fuel injector control module, which comes up on emps.

I cant read anything on engine , everything else is working. Ive seen quite a few people have the same problems, but no solutions. Please help

I have same problem and nothing seems to work, I have replaced the ECU, Steering rack and the P/S light would not go away. Can the electric motor have failed, where is it located?

What exactly is the problem? No power steering? OBD port not working? Please be specific as your content doesn't align with the old thread.
