Thanks for the info. it appears to be "operating" correctly (I think)... I am just getting everything buttoned up to actually start and run to begin tuning. I have noticed that when I turn everything off for like 10 seconds, switch tanks at the dash switch and then turn key to the "key on" position that I don't hear the valve switch or the pump turn on?? I am wondering if the ECM "thinks that the pump is already primed, so it does not send a pump signal? I believe that I have things wired correctly....
