My neighbor has a 2008 Grand prix V8 that won’t turn over. When the ignition is turn on the starter does not turn and then the horn honks once, you hear clicking sounds in the engine compartment and inside the car and the service display goes through each system indicating that it needs service. We unsuccessfully tried jumbing the battery. Any ideas?
Still sounds like a dead/weak battery… Try jumping again, and make sure the conections are on tight… Also let the car doing the jumping run a while and try to start the dead car with the jump car reving up to about 2-3,000 RPM… Poor quality cables can make jumping a car very hard.
