No start, I recently just changed my oil pick up tube?

Hello, I recently just changed my oil pick up tube and dropped the pan. Cleaned it up and put fresh oil back in. Once I got everything back together. The car started and I heard some ticking, so I drove it two blocks over and the car completely shut off on me, so I literally had to push the car back home. Once it was home, I put the key in the ignition and the car will not start and I have all light power. Next morning, I took the battery to get tested and they say it was bad so I was like okay maybe this will fix the no start, so I pop that in and crossed my fingers. I literally got nothing, and I still have all light power. So, I went with my next conclusion which was the starter relay. Went and bought that and still no start. Please help.
