IP not working - cjcosta - 10-29-2013
Hi everyone,
This weekend my w460 let me down in a Offroad raid.
OM617a MW IP
Start losing power, then completly dead. No fuel in the injector lines, just one is working.
Primary pump is working ok.
Any sugestion?
Best Regards

How did you test check primary pump? Sounds like the problem is fuel supply. I doubt that all the plungers and barrels all failed at once. Unless you feed it gasoline.

I just had a failed lift pump the other day. It could pump with no resistance but, under back pressure it couldn't do anything.
This sounds like a fuel supply issue. Clogged lines, filters, dead lift pump. Did you try to open the injector lines and crank the starter?

Problem solved.
Got to go to a dieselshop. They found some dirt inside the pump.
I tried to start the engine and the lift pump was pumping a lot of diesel.
Thanks to all.

Another thing that can cause problems is if the tank vent it plugged, the tank can get a vacuum in it and then the pump can't pump as hard as the tank is "sucking" and cause issues
