Driver put gas in this diesel. Having this code stored in your Powertrain Control Module can be a safety issue. I'm aware you should replace everything in the fuel system hands down. Injector pulse duration is determined by the measured rail pressure and the target injection fuel into each cylinder. What are the causes of the P0093 code? I originally started with feeling like i was in limp mode but even in limp mode barely getting power.
The solution is here : Mercedes-Benz Vito P0087 Possible Solution : Disconnected, dirty or fouled spark plugs are common causes for engines that won't start. Reassemble the fuel pump and related components, clear all codes, and see if the engine will start. Usually located in the fuel tank, an electric low-pressure fuel pump sends fuel to the high-pressure fuel pump, which is mounted on the engine. In some applications the pressure regulator is located on the fuel rail and operated by a spring with vacuum assistance obtained from the inlet manifold. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. If this happens, you will need to diagnose and repair it first before you can turn your attention to the fuel pressure itself.
