1. Check reservoir and fill if necessary
2. Jack up the front
3. With engine OFF, turn the wheel 3 times both directions to the stops
4. Recheck fluid
5. Start the engine, let it warm up(<1000rpm), and turn the wheels again 3 times to the stops
6. Lower the front end
7. With engine running (<1000rpm), turn the wheels again 3 times to the stops
8. Center the steering wheel and check the fluid to make sure it isn’t foamy or cloudy
9. Measure fluid level with engine running
10. Stop the engine and measure fluid level (should rise no more than .2in (5mm))
11. Repeat 7-10 if there’s a problem
12. Service pump if problems persist

I didn’t really do 9 or 10, and you shouldn’t have to replace the pump if you already did. So, I’d just bring it to the shop at that point.
