TMT, you are correct. My reading at inertia was KOEO. Started chasing plugs and seeing 5.4V at pump now KOEO. I checked/cleaned the plugs you referenced. About to clean the 2 grounds you pointed out in an earlier post. Are there any other known connection points to check? Really don’t want to fry yet another pump. Thanks.
My truck already has that harness installed, so likely the pump had been changed prior to my dilemma. Ran truck for about 10min w/out issues and saw 12.3V at pump plug. Going to button it all back up and road test in neighborhood to make sure everything is correct.
