Hard to explain like this but here goes.I was driving down the road one day when I heard a ticking noise like a lifter so i put my foot on the clutch and it died.I pulled over and fired it back up started fine so I carried on.About 2 km down the hwy it started again I touched the throttle and there was no response then I pushed WOT and it came on hard and stuck there after stompping the peddle a few times it went down.It's done it quite a bit since then and it seems worse when idling for a while or in town.I know when it is going to happen because it will crank for a bit when starting.Truck has 370hp marine injectors and previous pump work unknown.Any help where to start looking on the pump would be nice.Thanks

I would probably have the pump removed and sent to a shop to have them go though it.

Most of the time when a pump goes into what we call runaway mode(the pump sticking in WOT or not shutting down even though the shutdown solenoid is functioning)its a internal issue of some kind.Throw in the fact that you know little about the work done internally and it would off and out getting looked at if it was mine.

x2.sounds like internal pump issue to me.

I pulled the AFC off today to check the fuel plate and found what appears to be the stock fuel plate FF and the gov arm was bareley catching the bottom .Would this arm falling under the plate and getting stuck cause the throttle or rack to stick?Or any of the other symptoms ,no start ,run away ?Adjusted it anyway but no insurance on truck right now (and im in northern Alberta right now with Albertans and snow)so I could only warm it up and rip around the neighbourhood ,which has caused high idle and throttle sticking before but could not be sure fix is complete yet.Also thought about broken gov springs throttle also seems to go higher than norm 3100+ and snap ,crackle ,barks
