Vp44

What are signs your VP44 could be going out?
Every once in a while......................
I hit the throttle, and nothing happens.................
I was wondering if this was one of the signs it's going out, also what else it might be, like TPS?
Someone throw me a bone here
I don't think it'd be a bad idea to make this thread sticky either considering it's the 24v's (Non-CR) only weak spot.

Sounds like a TPS to me... you could try reseting it

A good place to begin is by recalibrating the APPS and see if that helps.

A few signs a 44 could be going out are: hard starts when warm, loss of power, stumbling when running, throwing codes, white smoke to name a few.

Nope Bcumminsmeck, the dead pedal he described is the most common sign of one going out. Usually after the dead pedal goes on for a while it will just die out or start showing the other signs/codes Bouncer described.

here's a hypo: Lets say your cruising at a constant speed, let off and when you step on it again there's no response for a few seconds? or from a stop, no response for a fe seconds?

Well I think those are all logical guess's. But I can't help but fear the worst considering I've been running a comp box for a year now.

you've been running a comp for a year and you don't have a big fuel line kit/ bigger pusher pump right? If thats the case, I wouldn't be surprised if you've starved your vp a couple of times.

I wonder if the only reason it's still running is because of all the additives and BIOdiesel I've been using?

I know the summer I bought it, it started slighty hard, but now in the dead of winter, without plugging it in, I still don't use the wait to start thing. (Hotbox, Heatgrid, Toastoven, etc.)

I don't know. The Cummins Guardian angel must be on my side.

Not trying to be rude, but you really need a gas motor if you are going to treat it like that. Lots of expensive damage can result from not letting the grids kick off before starting the truck.

The grids cycle on and off while your driving the truck with the outside temp below 50 or somewhere in that area.
