Injector pump stayin on

[Hillbilly hotrod]

The other day went to start my truck 05 F350 ,it was idling like it had a miss. I got in to tap the throttle and there was no response. So I shut it off and tried restart but it wouldnt. So I cycled it a few times and it fired and seem to run fine but it sounds like the injector pump wont shut off. Anyone know what might be going on?
Thanks

Injector Pump?

The 365 does not have an injection pump, just a high pressure oil pump to drive the heui injectors under fuel delivery pressures. You need to describe the noise in better detail so we know what you mean. As far as the throttle response you might have a high pressure oiling issue but it could be a number of things, is your check engine light on? Need more information.

It is a buzzing noise that is coming from under the hood. It used to come on and then go off, but this morning it just stayed running. It never threw a light but after driving it for a while everything is back to normal. I dont get it, maybe it was pissed since I havent drove it in sometime.
