Alright so like the title said, the car won't start. Last night I was driving home normally like I always do, came up to a red light and began to downshift like normal. I would hear the occasional light popping sounds from the rear exhaust leak which didn't concern me at all. This time as I was downshifting I heard the same popping accompanied by a louder pop which almost sounded as though it was coming from the middle or the front of the car. I get closer to the red light and that loud popping has happened twice now until I begin to come to a stop; before I stop the warning lights turn on and the car dies, I turned the key off immediately, held the brake and engaged the parking brake, vehicle in neutral. Trying to restart it now, clutch to the floor all I hear is a whirring sound and nothing else. Did this a couple times with no luck, had to get it towed. So at the house I get curious and pull off the timing cover, no slack belt appears undamaged, no debris anywhere that I can see. Slave cylinder appears to be engaging just fine, moves when I push the clutch. When I put the vehicle in gear and try to start it, it lugs a little bit in first with the whirring sound, 2nd sounds a little higher and faster, 3rd is fastest but still no start, just the whirring sound. Clutch pedal feels like it is weaker than before, less pressure/resistance I'm at a complete loss, and I'm new to DSM; hopefully someone on here has an inkling of what might be the issue.
