1990 250 7.3 IDI Shut off wont restart Bad Injector Pump?

180K

Had the truck towed back in. So far i have Checked the following.....

Fuel Flow Before the filter housing and fuel flow After. I get a Healthy Spurting Stream when the motors turns over.

Check the Solenoid in the Injector Pump..getting power and it is clicking.

I dont think the truck has elec fuel pump...Just the Mechanical on the Engine block correct?

however i am getting No fuel from the injector lines so im taking the pump to a Shop that has a Flow bench to tell if it is shot and for a possible rebuild.

So am i missing anything?

Also what is the sensor in the Injector Pump Housing? 2 wire switch.

losing prime would be a good suggestion too, do your injector return lines seap or leak at all? thats a big reason IP's lose prime as they do have an internal check valve.
