Having a weird issue hoping I can get some help! 2007 N54 E90 single turbo with dual walbro 450s. Car ran fine for few weeks, never left garage just short start ups while worked on other things. Then one day would crank and no start. Lpfp is not getting full power. Ive tried 3 EKP modules (coded in all of them) getting 12v to ekp on main power wire, 2.7v at small blue wire key on and only getting 1.75v at the fuel pump connection, same voltage for all three 3 ekp modules. Have a spare set of wires spliced from ekp to fuel pump still getting 1.75v so I know its not wiring from the module to the fuel pump. The EKP appears to be getting full power but not sending it out, ekps are good tested in other cars. Any help or ideas greatly appreciated!
