Not getting fuel
I have an 83 F350 6.9 IDI
It just died and wouldn't start. Replaced lift pump. injection pump replaced three years ago. Bypassed fuel/water separator -a year ago. Not getting fuel-not sure of where to look. Nothing comping our of bleeder valve on fuel filter.

hook up the lift pump so it draws out of a jug of diesel.if it picks it up then the new lift pump is good and the line to the filter isn't plugged up.
then you'll know to look at the fuel line from the tank selector valve (it might be bad) or the pickup in the tank.
first make sure you've got half a tank of fuel.if she's below 1/4 tank it could be a tank pickup issue.

you must confirm that it is a fuel problem, are you certain the glows are working?? it is not likely the fuel system will break when you shut it off. its more likely some thing wrong with glows..be careful not to over heat the starter...

things done
the truck unfortunately is an ether baby at least for now. When I switch the tank selector I get two different readings so that's ok I think. I can try to pull fuel from a container as suggested. The lift pump is brand new.

I would recommend dropping the tanks to fix the cone of doom and switch to manual ball valves while you have the truck off, then you never have to worry about the tank switch getting stuck and leaving you stranded, it is one of the single best mods I have done to my truck, I would do it on any new ones I buy before making them daily drivers.

I am trying to determine if the lift pump cam lobe is worn. I need a diagram -anyone know of a diagram of the lift pump cam? All other things check out -plenty of fuel in the tanks, etc.

What kind of diagram of a cam lobe would you be looking for? It's a lobe on the camshaft. Not sure what else there is to know about it. It's harder by a long shot than the arm on the pump, so the engine would likely have to have several million miles on it, over dozens of replacement pumps, to show wear.
