I have a s500 w140 with a m119 motor which I have to crank twice for it to start.I have changed the fuel filter fuel pump.did diagnosis came up with an error code 018 crankshaft position sensor L5 magnets not recognised. i also suspect the fuel pressure regulator but i dont know how to test it. the car has one fuel pump. also what is the pressure of the fuel at the fuel rail schrader valve?. any input is sorely needed.
