    Need help finding problem with 2001 LB7. The truck starts and idles fine but when the pedal is pressed, NOTHING. I have checked the fused and can't find the problem. Has happeded once before. Let sit overnight and problem went away. Any idea where to start?

    did u change the fuel filter ? perhaps letting air in, or not primed up..

    had that problem once before, needed more pumps on primer on top of fuel filter.

    Problem was corrected today. I replaced the Pedal and the truck was still doing the same thing. I took it to the dealer and they hooked up to the computer which told them the pedal was bad. The one I put was only a day old and that is when the digging started. In the end the wire harness to the pedal had a bad wire which they replaced. The good thing is they only charged me $90.00 for two days of trouble shooting.
