my 94 12 valve when you rev the engine in neutral it breaks up and shoots white smoke. The truck has 140hp ddp injectors and a #100 fuel plate. I dont know of any pump work done to it. Also when your going down the road just cruising the truck acts like it wants to stall kinda like being in to high of gear. Just got the truck and dont know much about them. The fuel plate is pushed all the way back because the clutch cant take the power. Im savin for a south bend. Any ideas?

 

timing? that would be my guess

 

your talking timing on the pump right sorry probably a dumb question kinda new

 

yeah pump timing could be off, someone will chime in and give some more ideas im sure and im not too much of a 12 vavle guy but im sure if you do a search you will find an abundance of information on pump timing. it does involve some special tools though

 

The nuetral reving with popping and white smoke gives a hint of timing being retarded. Just an idea

 

how would i go about advancing the timing

 

The timing tool and some time. I have done several trucks and its not that hard. I believe there may be some other ways that guys have developed but im unsure! I just use the timing tool from snap-on.

 

my truck breaks up and white smokes when its cold. im pretty sure these trucks just dont run good untill they warm up, either way i plan on doing the timing as soon as a get a dial indicator. from what i understand you just need a dial indicator to do timing, right? iv been needing to replace my dial indicator anyway...

 

Mine takes a really really long time to heat up wich i cant figure out y that is either if anyone has an idea.

 

u need a dial indicator, the base that screws into ur DV (delivery valve) hole, a DV socket to remove it, torque wrench to tighten it back up, and a gear puller
