Reading fuel pressure using an OBD2 scanner
I have a 2012 Citroen DS3 1.6 THP (the notoriously bad Prince engine, don't come for me!) and it's showing all the signs of a high pressure fuel pump failure. I know this is a common thing so I want to just make sure it is before I start paying to get it replaced.
A bit of background first however. This car has not been on the road for two years. My Dad was fixing it up as it had all sorts of issues and got them all sorted. He got ill and the car sat in the garage for months and months and then it started misfiring on cold (on one cylinder). Plugs and coils replaced, and new fuel injectors on cylinder 2 and 4. There has been the error code for low pressure come up a couple of times on my OBD 2 scanner when I've started it up, but this is sporadic and does not happen every time. For clarity, the car is still off the road (no MOT or tax etc) it's sat on my drive so has not been anywhere.
I would very much like to check the fuel pressure to see if this is actually what the problem is. I have a Motopower scanner model number MP69033 and I have NO CLUE how to get to the fuel pressure reading bit! Does anyone know where this is on this OBD2 model? I don't need to see exact figures, just if the pressure drops when I rev the car.
If you know, please tell me as I cannot find anything it seems on trusty YouTube.
