Getting no power to the fuel pump but getting power to the fuel pump driver module but the thing is I was getting power to the big RED/WHITE and PINK.  Little GREEN/WHITE barely red but when cranking gets brighter on the driver module a couple days ago but only to RED/WHITE wire now (5/10/20). A couple days after I checked the wires.The PINK and GREEN/WHITE wire goes to fuel pump the big RED/WHITE is main hot wire from ecm. I checked fuse for the fscm its good. Grounds is good (redid them). My only question is what causes them 2 wires not to get volts to the pump when the driver module is getting power?
