Hi
This vehicle has had lots of people 'look' at it and it has now ended up in my lap!
It is low on power and MIL light is on DTCs = P1220 Fuel quality control.
I have looked at Vauxhall TIS and it says that it could be air in the lines, I have rigged up a remote tank and attachd it to the filter housing, still the same. Apparently the pump has been rebuilt, I am still waiting on the owner to find the bills. I have checked on live readings for the engine RPM and pump RPM which shows half enine speed, this appears to be correct.
