My air dog fuel pump has stopped making the noise when i turn on the key everytime.it's the origianal air dog system it's made the pump noise everytime sence i'd had the truck now nothing! did lose power on the highway yesterday for about a 1/4 mile, it didn't die but no throttle acellec then it just picked back up. thought it might have been cuz it was -6 here yesterday morning but then noticed no noise from my pump.truck seems to be running fine still though. Is it time for a new air dog???? Oh and i don"t have A fuel pressure gauge in it yet. Any help or thoughts would be apprecatied.

 

Try this. Bump the starter, but don't crank the truck. And leave the key in the run position and see if you can hear the pump running under you. It should cycle for about 20-25 seconds before shutting off. Plenty long enough to hear if its working.

 

Maybe there is something stuck in the gerator gear?

 

well found out i'm blowing the 20 amp fuse. now have to find out why, went though 5 fuses already.

have the p0216 code!! and still blowing the fuses think i'm going to be screwed.

 

Blowing the fuse, dead short or stuck gear as Scott said.

Oh crap, not the p0216 code!

 

Locked the motor is my guess... Pull the back cover where the gears are for the pump and see if you can spin the motor by hand. Probably fired the vp up when u were on the highway when the pump quit...

 

sounds like time for a new injection pump and a new air dog...pm me about the injection pump if you do end up needing one...i've got a used one that's only got a couple thousand miles on it that i'm thinking about gettin rid of and doing a p-pump swap...its a scheid hot lighting vp44 add's 100hp would work pretty good with your lil 65hp bullydog box

 

i was on the highway when i had a dead peddle the first time, other then that time the truck runs just fine. found the instruc on the AD going to clean the gerator gear in the morning, see if it help's. let ya know what i find out. thanks all.
