I Bought my scanner fro Super Cheap it is not Bosch second down in price it can read fuel rail pressure only from rail sensor there is no other sensor on the fuel line other then fuel level in the tank

I am going to get into fuel feed pump connector tomorrow and if it is no oxidation on connector how this tell me about pressure it can deliver?
I apparently had a dirty fuel at some point recently

I don’t get what you are saying there is a fuel pressure sensor on the fuel rail if you check the pressure with the engine off that will give you the low pressure pump value . When I said go to supercheap I meant get them to use their proper Bosch scan tool to check fuel pressure. But at home lift the rear seat base remove the round black cover and unplug the fuel pump plug and check for melted pins this causes the low pressure the in tank pumps very rarely have problems . I won’t be responding again I’ve tried to make it as simple as possible.

Thank you very much I will do this today (if connection will look good I will order another HP pump from reputable source this time around)
Today morning cold engine, ignition on fuel rail pressure is 660kpa (6.5Bar or 95Psi) and upon start an engine light conning on it was 700-730kpa
