I recently purchased this engine and have been trying to diagnose an electric issue I have been having with it. When I turn the key my relay is not clicking and I’m not getting any power to the vst high pressure fuel pump or injectors. The motor does start and sputters with starter fluid. I think the previous owner may have reversed the polarity. I have changed out the relay and changed the one 30 amp fuse I could find as well as installing a new ignition switch. I don’t think the ecm is bad. Any suggestions?
