Have checked all fuses and relays to be good , did the WT ground method also the pcm ground splices and rebuilt the ground under the battery on both of the studs and added a ground up to the negative battery post, my issue is the truck will just shut off a few minutes Into driving it and I can’t for the life of me figure out why , when truck shuts off it takes about 5 minutes or so for the wait to start to come on so that I can reprime the injectors , my fass relay harness doesn’t make much sense to me because I didn’t install it , and I ran mine on my 02 differently but it’s been so long I can’t remember not sure if that could be the issue
picture 1 green and red connect to I believe the factory lift pump plug however the red which is spliced into the black wire isn’t connected to the relay , 2nd picture is green from fass connect to the green from the factory lift pump plug which also runs to the negatove battery terminal on the white wire of the relay , 3rd picture red from relay to positive terminal on battery, black from relay to the fass pumps red wire and yellow goes inside the cab to a switch from the switch to the inside fuse panel add a fuse ,
