hard cold starts
when starting cold the motor cranks for about 3-5 seconds before starting, it surges twice to about 1800-2000rpm and then dies. takes a few cranks to start again but then it is fine. Any ideas

if it's air intrusion it's probably the return lines. I would go out and pull the fuel filter in the morning and see if it's all the way full after sitting over night, if it isn't then it's air intrusion. In the meantime I would get a test light and test all the glow plugs. Alligator clip on positive battery terminal, pull off gp boot and touch tip of test light to top of gp... if it lights up strong the gp is good, if not then replace with berus.

It is generally in the return line system, but can also be in the line from the pump to the filter, the pump itself, even the schrader valve in the filter header. Look for any wet,damp spots if you are lucky you will see it, but air will leak in without it being bad enough for diesel to leak sometimes.

just checked the fuel filter after truck sat for about 36 hours and it is completely full. being new to diesel and all i am not sure where the gp are located, do i have to remove the valve cover. Also when the block heater is plugged in it is extremely load you can feel the vibration on the grill guard from it. Is that thing going out as well

Glow plugs are located on the top of the head outside the valve cover. Look next to each injector and you should see them.
Sounds like your block heater might be shorting out.. I would check the chord for bad spots.

it would not surprise me if more than half of them are bad. Are these something that needs to be ordered or do the local auto part stores carry. I do know that there is only one brand that you guys say to use so i want those ones.
