Fuel pressure at idl is 3400 wot is 6500 won't start
Unless u use starting fluid will run but not good
Has new injectors code is p0148 what could the prob
Be ?
Fule pressure sensor
Fca - fuel controlled actuator
Was replaced too

 

Any one have an idea what it is ?

 

Unplug the FCA and see what pressure you get. Tighten your crossover tubes be sure you installed properly!

 

AS a guess, your injectors are not up to par or the install was pooched.

What exactly did you get for an injector? What cross over tubes?

P0148 is low fule pressure, have you checked to make sure the LP is working good?

 

Start at LP, and go from there.
