STOP START ERROR

Got this problem can see its quite common but seems not to easy to fix started with the emission's light sparked up code  P308D high pressure fuel pump changed pump fuel rail sensors not cured have ordered a lift pump from Germany should be here in a few days.

What l really need is some feedback to see if these problems are connected or some kind soul in the Birmingham area to run a scan with this Ross- Tech stuff looking at some of the data its like looking into a hedge. (l know l am a tech dinosaur)  wouldn't expect it done for free if anyone can help.
