Do you remember where you bought the pump from. I am also working on a 08 GMC Yukon with the same issues. I looked at the connectors and found one really in bad shape. Melted the housing. So I cut the wires and bought the 4 plug connectors with pig tails and installed them. Now that I am done, the Yukon will not go into engine off mode. So in short I screwed something up. It is not getting a signal back from the pump after 15 seconds. I rechecked my work and made sure the color per cable matched up from the pump to the controller. Pin 1 RD, 2 Bl, 3 ye and 4 bare. On thing you mentioned is the 60 AMP fuse. where are the 60 amp fuses. Where are they located. I do not find reference to them in any of the 3 fuse boxes. Before I redid the cable connectors, it used to go into engine off mode. Just the jerking issues. Any help would be appreciated.
