fuel delivery problem 99 c230

[1whonoze1]

I have 60 psi at fuel rail but no fuel to cylinder. I've been told that I have two fuel pumps but only found the one external pump. The car runs with forced fuel through breather. Can anyone recommend the best route of diagnosis. I'm thinking fuel pressure regulator then crank position sensor. I pulled code P1235 but scanner recognized the car as a ford, then Mazda and then a Lexus??? All three attempts pulled the same code and suggests fuel system problems
