I have a 95 Ciera SL 3.1 that while driving will cut out completly. I'm talking everything cuts out, no lights, no hazards, no instruments, no power to anything, its like someone has disconnect the battery while im driving. I have a new battery, checked all connections to battery, alternator, starter and everything is good and tight no corrosion on anything. Battery is putting out 12vdc. I have looked at a wiring diagram for this car and after looking at it alot of this points to the EMC. I have checked the connections ast the EMC and it looks good too. No corrosion and good connections. Am I going in the right direction with this? Another reason I'm looking at the EMC is that I can disconnect the battery overnight and in the morning reconnect it and the car will start and run fine? Something is resetting, just don't know what. Please help.
