I drive a 1999 Pontiac Grand Prix. Yesterday, I drove to the store about 5 minutes away. When I went back to my car 10 minutes later, it wouldn’t start. Wouldn’t turn over, no clicking, just silence. Finally had to leave it there. When I came back 1 1/2 hours later, it started fine. Same thing happened to me this morning. Drove it 5 minutes, now it won’t start. What could it be?
Corrosion on battery terminals? Could have internal corrosion on cable. Bad battery? Security issue? Theft-lock?
Park/neutral safety switch. Try jiggling the stick while the key is in the start position and see if it starts, or put it into neutral and try there.
+1 for @keith. This problem is as common as dirt.
