  1. A problem that has happened twice in the last 2 months is that after parking my diesel Smart for half an hour or so, the engine won't start. The alternator and battery are good as it attempts several times to turn over the engine. After towing on a flat bed, it starts fine. Obviously the dealer is not finding problems. The bouncing on the flat bed seems to "repair" any loose connections or is this a bad area to look at? Are there special diagnostic tools that can trace the CAN history for intermittent loss of signals? After 13 years and 210,000 km I want to keep it going.
  2. Hi, I was hoping someone could help me with a little advice. I bought a SMART fortwo 451 Pulse MHD recently and i love driving it. however one thing that bugs me is that when i start it, engine cranks, making a sluggish whirring sound, for longer than usual before the engine starts then chokes at 2k Revs For example, it takes a second or two to turn over and when it does is seems as if i'm getting a weak spark, Whereas my cousins passion 451 2008 and brothers pulse 451 2010 start instantly and you feel the power of the engine and choke. i thought it could of been the spark plugs but i serviced the car last week, I've even removed the battery and re added it but it did't seem to do anything. could this be something to do with the MHD, Starter motor or even ignition coils or battery? i don't want to be going changing stuff that doesn't need changing :-) I was hoping someone could advise me what it could be? Look forward to hearing from you. Ammo
  3. Hello all, my 450cdi turned itself off after 5 minutes of running with fresh alternator and serpentine belt. After it turned itself off, it cranked, but wouldn't start afterwards. Any suggestions? Everything seems in place. Quick update: Same thing happened today. Fuel pumping through both send and return lines. Ran for a few minutes, blip of gas, and engine dies. Attempts to fire at first crank rotation, but continues cranking with no catching. Exact same thing happened one year ago, and car hasn't been started since then, until today. It seems to have both fuel and spark. Could this be a problem with air- fuel mixture?
