Hi...and welcome to the Forum
It sounds odd that the car doesn't start after fitting the parts, would be tempted to put the old parts back on and make sure the system is bled properly.
If the fuel pressure sender is not reading pressure then it won't start so ensure that fuel is present in the rail and then see if other components are responding accordingly.
What does the scanner report (e.g. fault codes, live data, etc)
