Thanks for the reply; Actually, I hit send before the entire message got typed. Here are more details:

Car is the 1977 911S; Within the past year, it has had new injectors, WUR, various vac lines replaced. Normally starts a little rough when warm, but smooths out after a minute or so and runs great. Lately (this has happened twice in the past month or so) I discovered thet the #1 cylinder is not firing due to no fuel. (Removed injector, left it connected, started engine, put it in a coke bottle, and observed no flow. Then, I disconnected the from the injector and at the other end on the fuel distributor, blew out injector and line with compressed air, squirted some gumout into the distributor connection for that FI, put it all back together and it runs fine. It seems that when I loosen the fitting on the distributor fir #1, no fuel comes out at first - like it is airbound or something, but after reassembling, it works fine. Do I need to take the whole distributor out and clean it ? or (hopefully not) does this indicate the need for a new fuel distributor ?

Thanks for any insight....
