When was the last time you replaced the fuel filter? I had a similar situation on an 83 chevy with a 6.2.

fuel gauge work right? sounds like its out of fuel or getting air in the system. is it leaking fuel from the fuel filter? fuel pump bad? smell any diesel in the oil?

cold there??...

If its 20 degrees or below,your fuel might have gelled up!..you need to use Anti-Gel additives in frigid weather..

Could be air got sucked in thru a cracked hose or a pinhole rusted thru a steel line anywhere from the fuel tank to the injection pump..any air that gets in will prevent starting until its all bled out somehow..(you can read how to bleed it in the diesel section here,under "Changing a lift pump"...)

Your truck MAY have an electric pump instead of a mechanical fuel pump--if its not turning on it wont run for long,although you might get it to start--the injection pump itself can create enough suction to pull fuel from the tank,but probably not enough to drive on!..

I found a cracked hose while poking around under the hood of my '82 K20 (6.2) yesterday,good thing I noticed it,the hose clamp cut the outer layer and the cover was coming off the fuel line,the one at the filter--and I saw fuel had dripped out(and right onto the exhaust manifold too! )...I'm wondering if that is why MY truck dies out once in a while...time will tell!..

welll damn i didnt know what else to do so i took it to the most reputable diesel shop around... at least 200 he said.... F%^k me
o well hopefully things will work out... how much are 16" newish clean alloys worth... maybe i could sell my wheels n buy steelies to offset the cost.. btw set of 5

We had a similar situation about a week ago with a hmvv and it was out of fuel

I sounds like your gelled up or your fuel pump is toast.....

Sounds like air in lines (broke line), gelled up, or no fuel.
