Lift pump has been replaced with a brand new one - first thing we did
I'm 99.9% sure it's electrical now - missing voltage at pin 1 and 29 on the ecu means the ecu is getting no power.
Gonna order a replacement brown relay and see if that helps
Hrmmmm after some more google searching it turns out pin 1 & 29 will only get voltage if the ECU is plugged in, because the ECU turns the brown relay box on, which then sends voltage back to the ECU. Crazy.
So all I can think now is the ECU has packed up - the immobiliser must have died in it so it's not responding to the BSI or PP2000
