I have the single connector 6 wire fuel pump ECU. The connector got replaced along with the entire fuel pump assembly, but I forgot to take a picture of the wires to put them back in the right order. The wiring diagram appears to be numbered and on the back of the connector one side has a 1 and the other a 6. So I tried to match them according to the numbers on the diagram, but currently no fuel at engine and truck of course won’t start. I’m at a loss. I’m trying to figure out what’s going on and determine if the ECU needs replaced. Any help is appreciated!
