The last few times the car started it sounded as if it was barely turning over but then it would fire up. Now it doesn't turn over at all, no noise when turning the key. The car has been sitting around for several months, is only started once a week or so and is rarely driven on the road. It is to be my son's car once he gets his driving privilege straightened out. I thought the problem was the battery and so had it on my CTEK charger today and after 7 hours the charger finished its cycle and indicates a fully charged battery. When I first hooked up the charger there was a sort of sizzling noise down in front by the starter or so it sounded to me. I unhooked the charger and reconnected the clamps and the noise was gone and the charging seemed to proceed as normal. Now the car still doesn't turn over. So in the morning I'm going to first check the voltage of the battery. If that's fine any suggestions on how to proceed with a diagnosis? The car is a manual and I tried depressing the switch button above the clutch pedal manually with my finger since I was messing with the master cylinder connection to the pedal and thought maybe there was a problem there but it still doesn't turn over when doing that. The plunger shaft on the master cylinder is now correctly connected to the pedal. Any suggestions are greatly appreciated.
