I've got a friend with a 1980 320i that simply will not start. It died suddenly in traffic, and has not run since. Vital stats:<p>There is spark and air. Engine runs momentarily if ether is sprayed into intake.<p>There is fuel pressure. The fuel pump runs, and if one disconnects the input hose from the fuel distributor, fuel sprays.<p>No fuel is getting to the cylinders. If you pull an injector, not a drop of fuel comes out no matter how much time you spend cranking.<p>Are there other factors here? From my understanding, Bosch K-Jetronic is a fairly simple FI system. Am I missing something?<p>Thanks in advance for any advice.<p>Eric Adair<p>

Best you get yourself a manual before proceeding further.
