Driving home from the beach last Sunday and next thing my 110 300tdi started to lose power and came to a halt . It was as if it had run out of diesel but I had half a tankful . Got towed home and this what I've found so far . No diesel to injector pipes , lift pump works and diesel comes to filter and injection pump is full . It will squirt out the spout the leak back hose goes on to if you crank the engine . The shut off solenoid has live and can be heard to click if you flick the removed spade connector against it , but not when the wire is attached and you just switch on the ignition . Removing the plunger and spring from the solenoid makes no difference . Where the solenoid fits is full of diesel . The rockers move normally when engine is cranked . Any tips or advice gratefully received .
