    So I have an issue someone can help with.
    My truck was not starting I dropped fuel tank after checking fuses relays and still wasn't getting any fuel to rail I checked pump by running hot and ground directly to pump.
    Pump ran fine.
    So I figured fuel pump control module after checking with voltmeter red and blue wire wasn't getting anything from moduel to pump with or without key cycled and blue wire should be a 12v constantly..
    But nothing
    Replaced module and truck started after replacing pump fuse but would only start then instead of idling it would just die . Did this constantly. Got frustrated then thought I wonder if me not tightening ground post but just putting it on post would cause this . Have yet to try but what else could it be
