My fuel shut off valve is not getting power and I can't think of anything else to check. I have a wire going from my radio to the shut off valve that makes it and the glow plugs work, but throws a code and puts it in limp mode, but it is still drivable. With out that wire, I get no glow plugs and no start. I've tried everything I can think of, do I have the wrong relay? I have a good 109 relay in the bottom right of the fuse box and a good 180 relay below the 50 amp fuse. I can't find anything to fix this. It has to be between the fuse box to the ecu or a mismatched relay. Any help would be appreciated, im out of ideas.
