Just to help anyone digest. If you want good help on issues, you gotta make it easy for people to follow you.

Sounds like a fuel pressure sensor... any codes you would like to share with us ? P0191 maybe.

Power steering pressure switch is on the same circuit. I have seen a few short out causing fuel rail pressure sensor codes and no start. Try unplugging it and see if it starts and stays running.
