Check engine light staying on. Code31&41

I have 91 pickup 22re. When code 31&41 hit me it made it run bad and now fuel pump will only work if I put a ground wire on green &yellow wire going into the open relay.

Answer this question I have this problem too

Is this a good question?

31 is vacuum sensor signal

41 is throttle position sensor signal

Im not sure how these are related to the fuel pump issue.
