Is there a difference performance wise between base model k20 oil pumps vs type s oil pumps? And are there any tell tail signs of a bad oil pump physically?

maybe could need a dealer relearn or if you know anyone with a snapon scan tool or cornwell there over 5000 scan tools that do everything the dealers do. Im thinking its sum thing electrical or something with the ecu. It might be a long shop but check all your grounds. I have a friend that we did a k24a2 swap and for got to connect 2 grounds, car would not start. Checked everything over to make sure connected and found the grounds.

Tried different cam sensors and crank sensor, still nothing. Well it started once and ran rough idk if it was struggling because of the amount of fuel from repeated cranking but didn't start up again.
Also
Cam sensors were off k20z3
Crank sensor was off k20a3
Don't know if that makes a difference I thought I read that they'll all work on any k series. I'm gonna check my ignition relay next i guess.

Well I don't have either, but I tries scanning with a paperclip to read the flashing check engine light. But it stayed solid. That was after Taking the battery out so I might of been a reset ecu type if thing as to not show any codes. And I'm about to head out to the garage to set the crank to TDC and pull the valve cover
