Cold Start Issue

Let the car sit overnight and then try cracking the fuel line at the fuel filter, pressurised fuel should spray out, if it does not then the fuel pump or FPR is not holding the pressure in the line so when you first try to start her up you have to wait for the rail to pressurise before the injectors meter correctly.

Here are the plugs-
