On the way home from store, I noticed that the red oil pressure light was flashing so I parked car and check oil level which was good. Turn engine back on (noticing a strange click sound) - oil light flashed again turned off engine & looked for leaks and checked for burn smell- none existed. Verified oil level once more and when to turn engine back on when clicking sound got louder and no real power to start car and more warning lights. If this would have happen without oil light while driving coming on - I would simply conclude I have a bad battery. Has anyone experienced this with a bad battery or does this mean that the computer got fried? Suggestions prior to me going to dealer?

The warning light means the engine oil pressure is low, not necessarily that the oil level is low. The problem could be the pressure switch, or you really could have low oil pressure. Driving the car with low oil pressure will damage the engine.
This is the "Low Oil Pressure Warning" light. It is RED for a reason! When this light (or any RED warning light for that matter) comes on, pull over and shut the engine OFF at once. Allowing the engine to run with insufficient oil pressure can cause a catastrophic failure in mere seconds. Such a failure can cost thousands of dollars to repair. This warning is most often the result of a very low oil level as indicated when checking on the oil dipstick. The engine oil level should be maintained as close to the "full" mark as possible - without exceeding it. Oil should never be allowed to drop below the "low" mark on the dipstick. If the oil level is shown to be between full and low, the light is probably coming on as a result of a faulty oil pump (the oil level should be checked with the vehicle parked on level ground, with the engine OFF). A faulty oil pump is unable to pump the oil with enough pressure to reach all the moving parts of the engine that require lubrication. Without proper lubrication, connected moving parts heat up, expand and seize. Moving parts are expected to move - not be prevented from moving. If your engine shut down, it may be the result of some of the internal parts seizing. Hopefully, this is not the case. Check the oil level and top off as needed to bring the level up and attempt to start the engine and have the vehicle checked by a trusted mechanic. Good luck!
There may be a misunderstanding here. Yes the warning light comes on when the oil pressure drops below 5psi. If the light comes on and the switch is working correctly, the oil pressure is not good. Any problem with the pump or the screen would make the pressure not good. If the oil pressure has been checked with a mechanical gauge and it is above 20psi, the switch or the wiring could be faulty. You would need to have the pressure checked to know.
Normally, if you get a oil warning light signal (flashing) could be a few things related to it. Number one, you are low on oil. Check your oil level and make sure it is at full level. Number two, is possibly oil filter is dirty, ( time for service,oil change) or problem with oil pump or oil pump pressure. BUT I would first start with checking oil level and then maybe a oil change.
Warning - your engine is not producing enough oil pressure and is at great risk of internal damage ($$$$$). Is the car high mileage? Is the oil level where it is supposed to be? How long since the last oil change?
That's the oil pressure light. Take it to an auto parts store like Napa or AutoZone, and ask the staff to scan your car (they'll do it for free). That will diagnose the specific problem. Odds are that you're a little low on oil.
check for proper oil level in engine with dipstick if ok.then install mechanical oil pressure gauge on oil pressure sending unit to verify proper oil pressure, if pressure ok. then replace the sending unit/sensor, if pressure not ok. , you may need to remove engine oil pan to check for restriction on oil pick-up tube screen. if ok replace pump. but also check clearance on mains and connecting rods.
The oil pressure sender unit is located on the oil filter housing.These do tend to leak at times. The warning light for this switch is a red oil can and a buzzer. Replace the switch. If warning light still comes on, have the oil pressure checked. The oil level sender warning light is an orange oil can with oil level under it. This sender is fitted on the bottom of the oil sump and can leak past the seal. If warning light comes on, check oil level. If ok, check for damage to wiring under vehicle. Senders do some times become faulty.
