LBZ: Buzzing noise from CP3

[JD4440]

Just finished installing some nozzles. Finally got the truck started after some cranking.
Thing is now for about 5 seconds when I "key-on" the injection pump makes a buzzing sound for about 5 seconds. 3 or 4 more than my TTS pumps prime time. What's the deal ??

My FPR valve buzz's too, has so since i can remember, all is well with it though:thumb:
I know thats the culprit because once unplugged it stops.

Just wondering if I hurt the pump cranking on it, Seems to still run ok. Thanks bud.
