This Is Getting Old Quick...
A few weeks ago I came home and my truck died in the driveway. (At least she got me home) The next day the water pump takes a dump in my driveway. I replace the waterpump after fighting with the fan clutch for a few hours. I then check the glow plugs with a light to make sure they all have power. (Still no start) I then replace the fuel filter. (She starts and strands me 50 miles from home) I tow her home and replace the lifter/fuel pump. (Still no start)
I'm out of ideas of what it could be unless it's the IP...
Any input greatly appreciated.

Do a pressure and flow test.....on the new lift pump.
Do pressure and flow test on the fuel pump at the Schrader valve on the filter (FSS- fuel shutoff solenoid disconnected). Remove the tire valve core and hook a hose and pressure guage on it should see 4-6 psi when cranking. Then do a fuel quantity test same place, should see 1/3 pint in 10 seconds of engine cranking, route fuel to a suitable container with a hose.
id you install the pump by the instructions......if the new style almost straight arm pump.
WARNING
This fuel pump must be installed only at the low position of actuator cam.
If the pump is installed at any other position than low cam, the pump will be ruined, the engine will stall and damage may result.
Incorrect installation will loosen the pivot pin and allows the pin and lever to come out of the pump and drop into the oil pan. This can occur immediately or after several hundred miles. This type of failure is not covered by warranty.
To ensure that the cam is at low position, it is necessary to use a mirror and a remote starter switch. Observe the cam through the mounting port and bump the engine around until a one (1) inch wide machine surface is observed. This is low position of the cam. Now complete normal fuel pump installation.

not arguing, just asking, do you know why it is that it will damage the pump like that? Never heard it, but would be good to know in the event I do one. I have had to put the one on my dad's 84 back after the bolt vibrated out and the pump was laying off the block loose. Never checked position as I didn't know. (he seems to have trouble tightening bolts, this kind of thing is a very common problem around the farm...)
Is it due to the pressure from tightening the bolts and forcing the pump in?

If the fuel pump is installed incorrectly, would it make some kind of metal to metal noise? Is there any way of telling if this happened without taking the fuel pump back out and inspecting the arm?
