SOURCE: no oil presure

If its an internal oil pump the cam will run it. Are you sure its the pump or is it the sending unit, is the engine making noise like there is no oil pressure, like lifter noise, rocker noise, knocking? Pumps do go bad, they have gears in them, a gear could have worn down or broke, or maybe a seal blew out, and it won't hold pressure. whatever, if its bad it will have to be chg.

SOURCE: Have no oil presure

do any one check the oil level first before saying it needs a oil pump, i just have to ask. your best bet is to know what engine you are working on, then either buy a repair manual from a local auto parts store or do a google search, the books give really good directions on how to perform lots of different repairs, also there is a lot of information out there on the internet thats free and usefull, just do a search and try different wording.

SOURCE: I have a 05 F-350 6.0L turbo diesel No start.

Check for fuel pressure at the primary fuel filter. there if you move the plug for the fan clutch you can see an auxillary plug on the filter housing facing forward and to the driver side. You should have 40+psi with key on. another way to check the pump is to listen for it to cycle on for 10 seconds or so after key on. Also check for lubricating oil pressure on the cluster gauge and then high pressure oil with a manual gauge. its needs to see around 600psi oil pressure to signal the injectors to fire. best way to check all of these is with a scanner that has data reading, which will also tell you if you have a bad ficm, ecm or sensor connection.

If you didn't change the oil, it's left over from before. If you did change the oil, then the new head gasket either wasn't installed correctly, or it's now blown, too.

Did you fully clean the old one off?
Did you get the head and block checked to confirm they're flat?
Did you torque the bolts in the correct order?

Oil presure

just a shot, but as with most pumps that are not sealed or submerged, they need to be primed.
