Bleeding fuel with rotary injector pump

It seems to take forever to bleed the fuel system on a Perkins 6.354 engine with a rotary style injector pump. Does anyone know the secret other than bleeding the lines at the injectors?
I was told that the injector pump was no good and that's why it starts so hard when it needs bleeding. I don't believe that because once the engine is started it runs fine and starts fine afterwards. Any advice would be appreciated.

Does this injector pump have an electric shut off solenoid? If so turn key switch to ignition position when bleeding the 5/16 bleeders on pump. One of the bleeders is after the solenoid in the fliud circuit.

check your lines and connections. usually fairly easy to bleed these engines. as andypandy says LIFTPUMP. check screen in liftpump. if any doubts just change whole thing ,not worth repairing

Bleed the two 5/16 headed bleed screws on the side of the pump fist to get all the air from the pump before bleeding at the injector. Also worth a check is the lift pump and all filters, it may be hard to bleed because you do not have a good flow of fuel.
