hello, I have already introduced myself, I am new to the group.

I upgraded the pump on my alfa 156 20v r65 to an r80. Everything is mounted but the engine starts and stalls immediately. I then bought a multijet boom with the 2 sensors.
what are the modifications and capture to do.
Thanks in advance

First what rail sensor are u goin to use, your oem or from new rail, if goin to use new one, then u maybe need calibration. seccond thing, disconnect fuel pressure regulator from the pump, and put that on the rail. That should work.
