i have a 1998.5 cummins i have a quadzilla adrenaline with pulse. my problem is when i punch it on a high level it will sputter almost like a back fire and some white smoke will come out in stead of the nice black, so i dont punch it any more. just the other day i cranked it up in the morning and it sounds like crap it makes a noise like it is not hitting on every cylinder and when i go down the road and try to give it a fuel it will sputter and white smoke will come out even when im giveing it just a lil thottle. could this be injectors or could it be my vp dieing or ...... please help

 

It sounds like your not getting any fuel presure from your lift pump to the VP44. If yours isnt pumping enough or its not pumping at all it could cause major problems with the VP44 like the ones you described and also cause your VP to die from not having enough fuel to lubricate and cool the pump. The lift pump is a common problem on these trucks I had two go bad on the 98.5 I used to have then got a after market pump and it worked great it always had enough pressure with bigger injectors and the Edge Comp it had.

 

Whats the fuel pressure,you have a gauge,if not get one and a least a EGT gauge to.That adrenaline fuels pretty hard.

 

the pulse monitor has a fuel press. guage right?

 

It does if you order the sending unit from Quad.

 

mine sputters also and i have plenty of fuel but it seems to be worse on the 1000 tunes i run the 3000 and its not as bad i have been trying to figure out why the sputter its almost scary i pulled some codes and i had a faulty speed sensor in the tranny it had also throwed the injection timing out of wack so i had to have that code cleared and it seems alot better
