The last three or four days my car has been making a clicking sound while it is cranking. I cleaned the connections on the battery and checked the voltage and its at 12.9 v. Yesterday I removed the starter lubed the gears, they were in good shape, with high temp grease and reinstalled. Still makes that [censored] clicking sound. Only thing I can think is the solenoid is going bad. Or maybe the starter relay? Anyways the engine turns over normally and starts fine. This an ac delco starter that replaced the original 50,000 miles ago. The original starter [censored] out at 80,000 when the clutch would not disengage and the battery had to be disconnected to shut the car off.
