When this error occurs what exactly is happening? or not?
What is that ring around the #3 injector with the single wire coming out?
And what does it do?
The QA has reached it's limit while trying to provide the requested value. The QA is an internal part of the injection pump. Possible causes include worn pump, bad ECU (unlikely) and wiring.
The wire to #3 is for the needle lift sensor
