I have a scirocco that's been sitting for awhile, like a year maybe a bit more, and it won't start. It started fine last time I tried to start it. I'm wondering what I could do to encourage it along. I've replaced the coolant and the oil. I also added some octane booster gas treatment to it. The starter was only 4 months old when it started to sit and worked great then. Now it makes a click and I can feel it in the starter. It also made kind of a fast clicking sound for a couple of cranks. I tried jumping it as well with my truck revved but it didn't help either. Any insight would be great,
