I recently posted under the title 240d fuel problem. I'm a little closer to figuring it out. I added a couple gallons of fuel and now fuel is flowing normally as far as the injection pump. Still won't start. If I loosen the connection to an individual injector and crank the engine over, there is a very weak flow of fuel out of the open connection. How strong a flow of fuel from the injector pump is normal? How do you test the injector pump? I think the area of the problem has been narrowed. I'd hate to replace the injector pump but it seems that could be the problem. Please advise.

 

almost certainly not the IP. Lots of posts on this common problem with poorly maintained cars,air in system, bad check valves, plugged tank filter and outlet, bad filters. This forum is great as is the pelican and others
