Lately my car was starting badly. After standing for a while it needed 3 to 6 seconds to start, and that time was increasing by the day. It appeared to have started after I had it serviced, the tire shop had a nice deal so I let them change my winter tires and service it at the same time... they appear to have messed up my car..
It's a diesel so that rules out some issues. Battery was fine, starter-engine sounds fine too. Temperature is still around 10 degrees Celsius so temperature can't be the issue... which leaves only one other option.. fuel line. Now this is really messed up, because that is really hard to mess up.. that is one garage I will never play with my engine any more.. Fixing and changing tires is what their good at.. but not engines clearly.
So I opened up the the space around the fuel filter, the car is old enough that you can still do some things yourself and new enough that every inch is jammed with engine parts. So in order to get to the fuel filter you have to remove some other hoses. First thing I do is check if all the fuel lines are connected properly.... somebody did not notice that one of the clamps is broken and will not tighten enough to enable an airtight-seal.
So changed the clamp, tried starting it the next day.. W00t! it starts perfectly!
