Clear DTCs and check again. Do you have communication with ECM/PCM?

HI,

THANKS for you help.
After clearing DTC, only code i get is shown below.
Car will work ok for hours, but when its cuts out then all fault code comes back again.

Code after Clearing DTC:-

Hi i would check the 5volt reference to your sensors,check out Sy Daiagnostics on u tube,

THANKS
I DO THAT NEXT

From what I recall about the Ford fuel rail pressure sensors, it's normal for them to over report by 10 psi.

So if you do decide to backup the pressure displayed by the FRP PID with a reading from a mechanical gauge, don't be surprised to see some discrepancy.

Right next to a stall you should check if you have com. with ECM and like Landroverman said cheking 5 volts ref. is a way to confirm if ECM is ON or OFF!
