Read somewhere lack of fuel or fuel cavitation doesn't help VP's.

Well check for, looks lines, mine did the same thing and it was a 20c clamp, near the tank and it was sucking more air than fuel. Had good fuel psi at pump, new filter, etc. Crack lines and see whta happens.

What do you think
P1688 (M) Internal Fuel Injection Pump Controller Failure Internal problem within the fuel injection pump. Low power, engine derated, or engine stops.

VP44 is DEAD!!!

Ether is just cheating the fuel system. Like on our military fire truck of the fuel cutoff is pulled the engine will still fire on ether for a short run and then die as well...

DieselMinded you know better not to use ether on a Dodge with grid heaters don't you??? Or at least pull the grid heater leads before using...
