Powerstroke stalling after cranking

[PS56RPD]

Ok, Here is my problem:

I have a 1994 Direct Injection Turbo Diesel, that I purchased new. I have a strange problem. When starting after the wait light goes out, it will start fine. Then when the voltage gauge starts to go to the normal range it jumps back and forth several times before going to the normal operating position. During this the Powerstroke will sometimes stall for a second and then start back by it's self. It will do this more than once at time and not at all others. The voltage gauge will move to the normal range sometimes with no issues and no stalls.

So far this is what I have done:
Checked glow plug relay, working fine, engaging and releasing as it should

Checked all glow plugs, test good, have replaced within 1 year.

Replaced fuel filter

Alternator charging good when truck running.

So please help out what do I need to do?http://www.powerstroke.org/forum/ima...ilies/ford.gif

I'm leaning on the oiling or fuel system being weak. The alt. is bouncing because on startup the GPR pulls a lot of juice and the motor running lower then normal RPM's will throw off it's charging ability. Testing the fuel pressure is easy. On first start of the day have a friend in the truck to start it. You with a dial type tire gauge good to at least 100 PSI climb on top of the motor and hold the gauge onto the schrader valve on the top/back of the fuel bowl. Read the pressure. It's going to bounce a lot so take the high reading and the low reading and average them for your pressure. Ideally you are looking for 65 PSI but anything above 45 will get you down the road. This will waste the gauge. The HPOP will need a tool/gauge made. Have a fluid filled gauge good to 3000 PSI and 3-5' of hydraulic line made to mount the gauge and a 1/4" NTP on the other end to screw into the head. Take a reading. Your local diesel shop will have a scanner that would be able to read these numbers and more but can be on the pricy side. Show up with a case of beer and see if the manager/owner would be willing to run a scan for a minimal fee.
