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.

31 is vacuum sensor signal
41 is throttle position sensor signal
Im not sure how these are related to the fuel pump issue.
