I tried to get the D4 running today, no luck. This D4 has a rebuilt head and new injectors and fuel filter but has not run in about 4 years.

The pony is bad so we drug it with a wheel tractor for about a half mile. I had already checked the fuel supply to the lift pump and filled the tank.

While in 4th gear, comp open, I bled the filter and had a good squirt of fuel coming from the bleeders behind the injection pumps. Now with comp closed I'm only getting fuel to one injector. I have tried various combinations of throttle open/closed, injector lines open/closed but three remain dry. It's a warm day and the head was hot from all the dragging and the one firing cylinder, so cold is not an issue. The engine will run on a shot of either.

What am I missing?
