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.
Ist dies eine gute Frage?

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