Every single relay was i
clicking and security light along with every
other dash light was going on and off. Disconnected battery held cables together. And found that relay was loose. Pluged everything up except one long black wire with ring terminal that show no voltages and another copper ring terminal that has 4 black wires on it low voltages (10.8v at full battery) with a google search it appears the low voltage wires go to the ground stud on transmission so I put it there...😔. I got the car to start but would die almost immediately. Checked fuel pressure and no pressure at rail tried to force the pump to run by jumping relay and fuse but nothing. I assumed maybe it was the security, so I disconnected battery for the night and went back to the car this morning and power reduced engine disabled no crank radio doesn't power on. Does anyone know what might be the problem?

sorry for the novel and thanks in advanced jake

update: car starts then immediately dies again no reduced power engine disabled but radio still isn't on and even with cel on reader says no dtc..
