  I could add a step by step BUT I will first ask WHY are you condemning the pump?
this is a major job -- flat rate @ 7hrs... that's for a pro in fully equipped shop.

Low pressure light came on, change the sensor yesterday no problems. Wife went to go to work this morning and light came on, now it is running rough.

You don't have to remove the engine, but you'll need an engine support adapter because you got to drop the subframe to get the oil pan out. Suggest you pick up some service information. Try AlldataDIY.

your next step is to confirm oil pressure, a mechanical gauge is used - often installed where the pressure sender is.
I would also scan for codes- would confirm if any sensor issues ie wiring etc.
I want to add oil pressure sensor not oil level sensor.

Going to garage, I have the knowledge but not the tools. Too old to put it on blocks and crawl under it. 210,000 on engine. maybe time for a new car payment.

210K and this issue: OK if tested REAL and low enough as you just said to run lousy because of true low oil pressure there's some pretty nasty damage going on already. If a pump alone was free it wouldn't make it right.
Got to know the warnings and heed them. Low oil level not to be confused and low oil pressure a different and very fatal problem to an engine.


Do check or have check with a gauge and if real causing it to run lousy think hard about keeping this vs IMO a marginal fix if a new oil pump even shut out the warning?

The first thing I did was check the level. just changed the oil two weeks ago. It was fine. Low oil pressure sensor was leaking so I changed that. ran it for a bit seemed ok. I have it being towed to a trusted garage and they'll let me know what's up.
