I have a 2004 GMC Yukon XL 5.3 . when i start the engine the oil pressure is at 25 psi, the after a few min it drops to 0 psi, and the low oil pressure warning comes across my dash cluster, and i hear the engine clicking and knocking. I immediately shut the engine off. each time i start the engine same results.. I feel it is the oil pump can someone please lead me to the right direction.
