had my truck for some time and has been running great (aside from a few easy fixes) but after replacing the glow plugs i all of the sudden have a huge loss of power! cant hear my turbo spool and even when i try to punch the gas i hit the floor without gaining any speed.
i have noticed a leak in my UP pipe clamps and a bad connection to my fuel pressure sensor and have the parts on the way..
my question is are these two problems goin to be all im looking at to get my power back? or am i needing to look somewhere else such as low compression or no fuel delivery, etc??
please help!!!

You are saying after replacing the glow plugs you are having an issue but is this immediately after replacing them or within some time frame of having done them? If this was instantly after doing them I would say that it is an electrical issue created during the work that was done as in possibly the connectors on the inside of the valve cover came loose which could cause a short which would shut down the idm on that bank of cylinders. I would go back and recheck all of your work. If you replaced the UVCH while you were in there and they are dorman harnesses, they have been known to come wired wrong.
