Lack of fire on 75 242 DL
 

I have a 75 242 DL that I am trying to get the bugs out of so it can be a daily driver again. I've been having a problem with fuel delivery. The pump works, I can hear it running but I get no cylinders firing. Changed the coil, have spark. Someone told me to tap on the fuel distributor and I was able to get it to fire up after doing that, but next time it would not start and the tapping didn't help. I'm going to change the fuel filter tomorrow and am hoping that'll do it but it could come back to the fuel distributor. This is first year for fuel injection, mechanical I guess. Any other idea appreciated. Thanks - Tom
