I have a 00 dodge... about a month ago the truck started to have somewhat of a dead pedal at times... usually just going to 1/2 power not to idle like a typical dead pedal siuation... It has got worse especially on cold mornings and long drives over a cpl hours.... I have wrecked 00 also that was running perfect before it was wrecked... I have changed tps, reset and adjusted the apps, changed map sensor and ecm... the only code i was getting was a 1693 and 0122 after reseting the apps the 0122 code went away, and when i changed the map sensor the 1693 code went away.. Any one with any ideas? It also seems to sometimes have a dead miss when holding the pedal steady... its almost like a hicup

 

Could be the VP44 is going bad, but it hasn't thrown a code yet.

 

The Vp is only about a year old and has about 20k on it.

 

unfortunately if the lift pump is weak an IP can be destroyed in very low mileage. i'm not up to par on the diagnostics of the 24v's but a starved IP is the same all across the grid. find some way to check lift pump pressure.

 

if Fuel press has been low it only takes a short time to kill a vp44. Thats what it sounds like to me.

 

my dads old 99 had that same problem, when was the last time you changed the fuel filter?

 

I have had a holley black on there since the vp was new... it olds 15 psi at idle and 8 psi @ WOT.... the pump has not been starved for fuel at all since it has been put on... I also read the codes after going to work this morning... the CEL light was NOT on...I used a generic code reader and got 0216, 0602, 0216,

 

P0216 is the VP44 death code . I'm thinking whoever you got the pump from, did a crappy overhaul.

 

Time for a Industrial Injection SO Pump and a Airdog Package Deal.

I know it sucks but get some good fuel pressure so it doesnt happen again.

The pump came from Diesel Injection In Louisville Ky it was there HOT ROD pump, well im going to switch the pump off the wrecked truck to see if this fixes the problem before i buy anything
