John what kind of fuel pump do you have and have you done any rewiring/hotwiring of the pump?
I believe you are right, I should never try to work from memory.

I have a relay so tha the fuel pump recieves full voltage all the time. My fuel pressure gauge shows that the fuel pressure is normalwhen this lean situation occurs.
