Had time over the holidays and thought I'd get my Ranger running. Don't get any fuel when I crack the lines to the injectors.
When I crack the banjo fitting on the top of the pump (closest to radiator) I get fuel leaking out. I'm guessing this is the supply connection since the other connection on the back of the injector pump is routed back to the tank. When I unplug and plug the solenoid wire I hear a click. What am I doing wrong? Any easy way to make sure pump is turning when engine cranks? I'm about to give up and sell it for parts. I disconnected the line off the fiter to the injector pump and connect a clear hose and sucked. Didn't see any bubbles in the fuel and lines don't appear collapsed.

There are "paddles" for lack of a better term, that operate the pumping action. Its an offset cylinder with paddles that ride around the outside of the shaft expanding and contracting. You may have a stuck paddle or two, which would allow some seepage, but not enough pressure with the lines attached.
Just a thought.
Have you checked the injector lines for blockage?

Loosen the fitting on the incoming fuel line at the pump and pump the hand primer to see if you have good solid flow at the pump. If so snug it back up and try to bleed the injectors. If no fuel still I would remove the fuel solenoid and see if the rubber tip fell off the steel plunger and is blocking the hole preventing fuel flow. If that looks OK then you may have a bad pump.

Just an update. I pulled all the glow plugs. When I crank the engine fuel vapors shoot out of the back two cylinders. Nothing out of front two cylinders. Does this give anyone an idea?

Is there a way to check the low-pressure bypass valve in the pump? If it sticks in the
"bypass" position fuel won't make it to the high pressure side.

Have you disconnected the lines at the injectors? You should disconnect all 4 and crank. If you still only have fuel at the rear two lines then disconnect the lines from the pump and crank. If you have fuel only coming from to ports then you need to open up the pump, and I am not skilled enough to guide you on that.

Here's a parts breakdown of the pump:  |
