2005 Chevrolet Silverado 1500 2WD Questions & Answers
2005 chevy silverado 1500 4x4 5.3L low oil
By your description, yes your problem may be in the oil pump, pickup screen. and/or clogged oil channels going into your valve cover /upper valve chamber. The ticking you hear is on the valve lifters and/or rocker arm.
Remove a valve cover, start the engine and see if an ample flow of oil is reaching the valves. Turn off the engine and inspect the oil inlet and return channels for sludge build up.
Not knowing your specifics I don't know where the oil sensor is located but it is probably accurate. Chev uses a side mount and internal oil pump if I recall. Either way yo may have to drop the oil pan to inspect and clean the pickup screen.
If the issue is in the oil pump it could be a damaged cam lever or pump chamber is clogged with grease-like debris. An old shade tree mechanic solution( which I have used successfully several times) was to warm the engine, shut it off, drain and save the new oil then refill with a gallon of diesel or kerosene to dissolve clogged oil chambers/channels. Run in place for 5-10 minutes or until the tapping goes away. Drain the kerosene and check for metal slivers, globs of sludge etc.This is at your own risk because if you have worn bearings that are only being held in place by sludge it could throw one. I suspect excessive sludge. This is a possible solution and if not resolved promptly, your valve guides will wear quickly and you'll be looking at an engine tear down.
The next step would be to remove the oil pump and inspect for clogs or wear. Note there may be a port directly on the pump which can be used to attach a meter for oil pressure at the pump--check your shop manual for your model. As an alternative you can add a half gallon directly to the oil and drive for 15+ miles but you will have to drain that oil/kerosene mixture and dispose of it. Good Luck.

Is your 3rd light working? If so check changing hazard switch turn signal assembly. It's inherent of 94 to 98 Chevy blazers. Don't ask me why but that's what I found in researching ..check for yours. I saw Chevy so I responded to you
How to fix codes PO300, PO332, and PO756
the PO300 code is for a random misfire in the engine, PO332 is for the knock sensor and PO756 is for the transmission not shifting or low vacuum.
I think if you fix the random misfire the rest will correct itself or in other words you need to replace the spark plugs and check the disturber cap for damage or carbon cracks and replace the rotor and you might be in business.
