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.
