Ok - my car is a 1986 Chevrolet El Camino - but they don't even list that model on this site...anyway - My car usually starts. 6/7 days a week it will start and then I will never have a problem again. When it doesn't it makes a sound like it wants to turn it over but it doesn't have the juice. When I get a jump and charge it up from the other car for 10 minutes, it will finally turn over and be good for another week. Nothing is left on, but there is the possibility that some wires somewhere are crossed and draining the battery - but I don't think that is it. It could be that the alternator isn't fully charging the battery either...or it might be the solenoid coil...any suggestions?
