Hello I have an 08 smart 451 convertable
the alt belt broke on me last night. So this morning I replaced it. It broke close to home so was a safe drive.
I took the car this am to get replacement. But again short trip and I let it cool before heading home.
Replaced the belt and car fired up. Ran rough but took it around the block.
Got home and it stalled pulling into laneway. But fired back up and ran great. Went about 5 min drive to work and car was fine. 5 mins later no start. Engine cranks but appears to have no spark. I’ve checked a few grounds and seem to be fine. The tensioner was a struggle so I’m wondering if I could have bumped somthing. Any suggestions on where to check that I am obviously missing
