need help, no oil pressure

Hi. I just got my engine back in after a new crank, bearings, and head. Now that it's back in and runs, my oil pressure light is on. I pulled the o/p switch and turned the engine over. Pumped oil out. Also tried a new switch. Still have a light. What now? Is there another way to check if I actually do have oil pressure? Thanks.

screw a oil pressure tester in and see what kinda pressure it is running at

Where would I get one? I looked at Autozone. I thought someone made something like that, but they only had fuel pressure and compression testers. Thanks

thats y i put a manual oil pressure gauge on my truck...

Just get a guage w/ a sender and hook it up, they should have em at autozone or summit or any speed shop...

this was on autozones web site:
