Ok here's where we are at. No fuel pump signal to the relay while starting. 10.8v between the orange and gray wires on the FP relay connector when ignition switch is in the on or off position but no start. If I jump gray wire at connector with known good 12v supply the FP runs and car starts. When I measure volts between Orange and gray wire with the car running I get 12v. Disconnected the OPSU, 3 wire, red,yellow,black, and tried to start. Nothing. Jumped and measured voltage at red and black wires at OPSU (2.4v) and nothing. Relay is good. FP fuse is good. Where should I look next? Seems like I am not getting a signal to prime the FP.
