Alright no need for a gauge with my new findings. My truck didnt wanna fire up at all a few minutes ago and my neighbor offered to push start it with his bobcat. I said yea good idea, so we got it fired up after a few tries and when i got it to start i had no response at all from the throttle. I tried pumping it time and time again and finally it caught and roared to life. Soon as i got it back to my driveway 15 seconds later it stalled out. I popped the hood and find a damn near empty fuel bowl. Ive seen it before after it runs and i know its supposed to be 2/3 full with diesel. Why on earth would it be damn near empty? Is it the fuel pump, or the lift pump? It has to be one of the two and i know enough aboout the truck to know that it has mechanical fuel pump. Just wish my nightmare was over
