Hi
I'm putting my old ecu back in and going for the obdtuner software, however having some issues
When I turn on ignition car powers on, but fuel pump does not prime, eml is on but when I try to read the code it says protocol error
What could the problem be?
If the battery in the keyfob is dead, does it mean immobliser doesn't work? does the fuel pump still prime if immobiliser isn't deactivated?
Thanks
