Not sure what is going on, but here is what has happened: was driving and noticed that the voltage was low (9-10) volts and battery light was on. Couple minutes later, car died while driving. Restarted immediately and drove for several more minutes, voltage fluctuated from 10-12 volts. No loss of power. Died a couple minutes later. Will crank but won’t start. Scanguage has no power, don’t have 12 v at efi relay, efi relay seems to be testing fine but gonna replace you see if that does anything. Replaced fusible link. Really thrown by the loss of power to the scangauge. Not sure where else to look or what else to do to figure out what’s going on. Not sure what other info is needed to help diagnose
