well i've been using either (ouch i know ) if the problem continues i will switch to a squirt bottle with diesel but i just took apart my fuel filter and replaced the o-ring around the element figure it might be losing prime through the filter???cross your fingers for me that fixed it it seems to start and run better already

No Start
Could be the Fuel pump. I'd check the Pressure.
Quick test is to open the drain valve on the fuel filter - turn the key on - a steady stream of fuel should come out. (catch the dsl in a can - less mess)

Hpop
Sounds like you at least have some fuel pressure.
Have you checked the oil level in the HPOP after letting it sit overnight?
There is a check valve that keeps the oil in the HPOP from draining back to the sump.

I changed everything in my 96 a couple months ago and it still will not start on the first try when it gets into the teens and it sits all night but with a little experimenting I found that if you cycle the glowplugs twice with a short 3-5 second pause between and then crank the engine for a few seconds release the key and hit it again immediatly it fires every time w/no smoke and very little rattle associated with starting a cold engine. Might want to give it a try.

If you have acess to a good scanner one of the test you can do with it is caled a injector buzz test. It should test all 8 at once then go inorder from 1 to 8 and listen. they should all be the same level.
