Engine won't idle.

I have a Cat GP40K with a Vortec V6 engine in it that would not idle. We replaced throttle body, Mass air flow sensor and the accelerator pedal sensor. The engine will now start for a few seconds, but hunts for idle, then dies out. We can remove the fuel supply hose at the mixer and hold it a away from the fitting about 1/4" and it will run. It dies out as soon as we intsall it. There are no codes.

Fact of the week
The origin of "love" as the score zero in tennis is debated, but two main theories prevail. One suggests it's derived from the French word "l'oeuf" (egg) which resembles the shape of the number zero. The other proposes it's related to the Dutch word "lof" meaning "honour" as players might be playing for honour when scoreless.
