95 Yj 4.0. New to me, previous owner moved the stock tank to the back, after moving the back axle back. I replaced with a motobilt 17 Gal cell and plumbed it all. Old pump was shot, replaced it, reconditioned the sending unit cleaned all grounds etc. When I put connector back together if i connect the wire going to the fuel gauge the whole pump is dead. Pull the wire (solid blue) out of the body side of the connector (leaving the positive..green/blk runner and ground..blk/red runner) fires up first turn. I really want a working fuel gauge..Any help would be so so appreciated. Pulled the gauge cluster out , cleaned the connections there, no help.
