Ok boss !!! I'm askin I'm askin
...
Went to NAPA to get new center o-ring... Turns out they could match it up for $8. Ended up getting a new Donaldson #P55-0587 (fleetguard FS1221) fuel filter with center o-ring for $15...
So tomorrow morning I'm gonna install the Donaldson filter...
Are these step correct ?
1)tighten threaded stud with large screwdriver
2)install new center o-ring after it is lubed
3)fill new filter with fresh fuel, lube gasket and spin on
4)tighten 3/4 turn with wrench
5)crack #4 injector and crank engine until diesel spurts out... Tighten injector
6)crank engine until she fires and hold throttle about half open until she smooths out and then let her idle a bit
If this does not work am I looking at a lift pump? I have no way of checking fuel pressure at the moment

Ok fellows ... Got the sermon ready for tomorrow morning... Plowed driveway with quad as we got about 8" snow last night... Finally got to the dodge this evening...
Installed new fuel filter and new center o-ring (lubed them with Vaseline) ... Filter was filled to the brim with fresh diesel... Cracked #4 injector and cranked until fuel was spurting out ... Tightened injector and cranked her till the battery almost died (30sec. intervals) ... She was coughing but no fire??? Put the trickle charge on overnight.
I cannot hear air sipping anymore ... The LP lever pumps freely (never builds resistance...as I think it would) ...
Am I looking at a new LP?
Should I crack #2 injector and work backwards on each one until each has fuel?

turning the truck over that much will not only drain your battery, but it will burn up your starter real quick! ask me how i know.

Ok so jfounder says that if the diaphragm in LP is shot there will be fuel in crank case oil ... If I pull the dipstick what will it look like if fuel is present?
Is fuel in the oil a sure sign of needing to replace LP?

For clarity, the IP is the injection pump. The lift pump is the pump behind the fuel filter.
The banjo bolt on the fuel filter exit has a 10mm bleed screw in it. Geno's sells a banjo bolt with a 1/8" pipe thread hole in it. That is ideal for hooking up a fuel gauge. If you crack the bleeder screw and operate the lift pump, either with the lever or cranking the engine, it should spray lots of fuel at you.
Anyway, it's looking at this point like it is not getting fuel. Either the lift pump is bad or there is a new leak between the lift pump and the tank sucking air, or the tank is empty.
The IP is likely OK. However, it does have a pickup pump in it which is adequate when this IP is used on much smaller engines, like a VW Rabbit. (yep, same pump). If the lift pump were bad, it would still run a little, which fits the symptoms. It is, however, very hard on the IP.
