my car works great 99 persent of the time and ones every couple weeks or so it won't start I can usaly wait a couple minutes and it will work but the last mounth or 2 it will work for a couple weeks then it will not start sometimes for a couple days then it will for no reasone start and work perfect againe
help me out all I can come up with is maybe the fule pump conecter is getting we then drying out I have a back sun roof leak

 

It turns over and doesn't start???
Have you replaced your filter, how about the fuel pump relay?
Have you check the fuel pressure at the rail?

 

yes it turnsbut no start and when it does start it idles very low then dies I did not check the filter or pump relay because I figures that that would make the car not work at all or run poorly and it works perfect when it starts
