So a week or so ago I had to pull up on the hard shoulder of the m6 due to the car going into limp mode. I was recovered home and subsequently had the car plugged into my obd11
The code that came up was the p0201 code which after a bit of research I found could mean any of the following, faulty cylinder 1 injector, harness that has an open or short, poor electrical connection in the harness or connector or ECM that is failing or has failed.
I then unplugged the injector and tested across the pins with a multimeter and resistance across it was a lot lower than the resistance shown across the other 3 injectors so i then assumed this would be the culprit and ordered a working 2nd hand injector. After fitting the "new" injector and coding it the car will now not run with injector 1 plugged in. it will start and run on 3 cylinders with the injector unplugged but if its plugged in either whilst running or before cranking the engine will not start. Before installing the new injector the car would run on 3 cylinders with injector one plugged in.
would anyone have any ideas on to what I could try next?? Anything I can do to trouble shoot or give a reason to why the car will no longer run with the new injector plugged in?
My next plan was to buy a brand new injector and then there would be no questions over the injector but as I'm sure you're all aware they aren't cheap!
thanks for reading and any help is gratefully received , Cheers John
