Last week I got the coolant leak fixed, but after last night of driving around the temp started to raise again, it got really hot that the front of the car started to make a whizzing sound even when I turned it off. So I drove it home after it cooled down only I didnt make it all the way home as I stopped at a gas station, it wouldnt start anymore, kept hearing the clicking sound. I assumed the battery might be dead so I waited till the morning to try and jump start it, only to realise I didnt need to jump start it because it started straight away after leaving it at the gas station for 8 hours or so. But as I drove it home, it kept feeling like the car was trying to cut out, when on idle the revs will jump and then drop back low, and then jump again and then drop again and keep repeating irraticly like this on idle. So I got home, and it died again and couldnt start it again with the clicking noise every time I try. Sorry for the long post but is my zed screwed? or is this just some electrical problems again?
Check for error codes first. The clicking noise is normally associated with a discharged battery or loose connections. Did it overheat or not?
starter motor get under the car and have a quick check that the terminals on the starter motor are all nice and tight. this may resolve the starting issue then you can go looking for the running problems
