Warm weather (above 50F/10C) after sitting awhile car needs to be cranked 5+ seconds or more. Definitely air in fuel line as about 1/2 mile down road car stutters for a bit. Every time. Cold weather starts fine. Ongoing for years. Fuel filter/pump/battery have all been changed to no effect.

  • What happens, in warm weather, if you let the engine cool completely (say over night)? Do you still get a hard start? How does the engine need to sit before it is hard to start? Have you tried replacing the fuel lines? – dlu Nov 26 '16 at 17:07
  • Car starts hard left overnight warm weather. If restarted within 15 minutes of stopping, starts fine. Negetive on fuel lines. – ATC Nov 27 '16 at 17:59
