sonny: No need to bleed the system........it self-bleeds the air out, as the pressure increases.

You seem to be getting fuel to the injectors........so, no need to check the plunger, however, I wonder if it is under enough pressure, to open the fuel injectors...........they won't work unless the pressure is high enough. When fuel, from the fuel pump (FP), enters the fuel distributor (FD), let say it enters "chamber A". There are two outlets in A; one to the cold start injector, and one into "chamber B". The fuel from chamber B then goes to the regular injectors..........this is regulated by the fuel pressure regulator (FPR), and the warm up regulator (WUR). Hence, the cold start injector is receiveing full FP pressure.........that is why it works.

The regular injectors receive a different pressure, regulated by the FPR and the WUR. The FPR is located within the FD, and the WUR is a seperate unit found near-by. The only way to test these would be to do fuel pressure tests, requiring a fuel pressure gauge, which will show what the fuel pressure is as it leaves the FPR. A "special" valve is needed, on the fuel pressure gauge, that can tell if the WUR is bad.

The fuel from the open banjo fittings should come out as a steady stream, not a dribble.

I hope this helps.
