Hi thanks for posting, the pressure tester was placed on the fuel pump and not the fuel rail sorry don't have the connection for my tester to attach to the rail. The engine seemed starved of fuel so after checking the pump I decided to change the filter as I don't believe it was ever changed. Before changing the filter the car would not start now it fires up but will not idle. Will order a pressure tester gauge connector and a fuel pressure regulator and let you know how I get on thanks.
