Compression test without oil pump
Just drained my oil to replace my oil pump. I get no oil pressure and was wondering if I'd be able to do a compression test without oil and an operable pump or do I have to wait til I replace pump and then do compression test?

Have you tried using a direct reading oil pressure gauge in the place of the oil pressure sensor to see if the oil pressure sensor is defective?
Why do you want to jump to a compression check when you have an oil pressure problem to deal with?

I drove about 1.5 miles with no oil pressure and wanted to check piston ring damage before I dropped pan and putting it back on only to find out rings are bad and having to drop pan again for repair

Like mentioned before. Did you verify that you actually have no oil pressure with a mechanical pressure gauge?

Yes there was knocking noise. And I was just thinking it could be something to do real quick to determine if there's any discrepancy from me driving without oil pressure.
