Hi I have a 2008 ML320 CDI Mercedes Benz. I had new injectors fitted, and the catalytic Converters removed. Now a fault code comes up: fuel rail pressure to low. The car cuts out while driving. Can anyone HELP ? Steve Marshall
It needs a cat converter to enable the ECM to function properly next low fuel pressure can be from EVAP system not venting the tank properly, failing fuel pump or faulty pressure regulator unloading too much fuel and dropping the pressure
at this point I would be looking at the EVAP system , then the pressure regulator
Testimonial: "Thanks Bill, The problem only started when the mechanic changed the fuel injectors, so I think the fuel pump is the problem. the old injectors were badly warn and probably didn`t need so much pressure. Regards Steve Marshall"
