I have a '76 300d and i got fuel with water in it out of an old container that was supposed to be sealed. I made it about 200 yards before it died. I have changed both fuel filters taken all fuel lines off and blew them out and turned the engine over until clean fuel was squirting out of the injector pump and i even took the injector nozzles apart and cleaned them to make sure there was no water stopping them up. I have also put new glow plugs in it. It will still not start it will try to hit a time or two when u first try to start it and then no more it just turns over. Any suggestions? Thanks
