Fuel Pump Constantly Runs

Hey guys,
I Replaced a bad fuel pump in the 1987 na z ,but when I put it back together the fuel pump is constantly on even when the key is pulled out. The only way to stop it is to pull the fuse by the clutch. What could be causing this?

did you disconnect the battery before pulling pump? might have fried the relay if you didn't

Yes, that was the first thing we did. I wasn't about to trust removing the gas tank/ fuel pump with power still to it hah. I was actually kinda thinking it would be the relay, but I can't find information on which relay powers the fuel pump and where it is at.
