driving on highway, i put my quadzilla up to highest level and put it to the floor... all of a sudden the pedal went dead and then the truck stalled out and now wont start.. is it dead VP? or TPS? gonna put code scanner today on OBD2

 

Let us know what the OBD says, what was your fuel pressure when you did this... and what has your FP been...you can also try disconnectiong your programmer and see if it will start up..

 

Do you have a draw straw for your airdog? That pump can suck fuel faster than the module in the tank can refill without modifying it. How much fuel does your gauge say you have? Dodge fuel gauges will just all of a sudden quit reading correctly. Mine was working perfect one tank of fuel and the next I was out of fuel at 1/4 tank on the gauge. I'd suggest you crack the injectors and see if you have fuel.

 

ok im gonna try all that and i had a full tank i just fueled it up.. i put a scanner on my obd2 and got 4 codes about the injection pump and timing
