Hi i have a 2002 lincoln continental with 31000 miles car doesn't start if i use a jump starter car starts and keep running for the time you deserve i test the battery and looks fine i test alternator and works fine even once car starts you can drive all day but next morning again won't start. So if somebody can give me any information about this issue let me know thanks ruben

My experience with the same problem turned out to be the interior light switch for the driver's door - I did not notice the lights stayed on after they should have gone out.
Switch may be stuck or worn out.

I have a 01 Lincoln Continental that wouldnt start. After paying $69 to the repair shop they told me that the alternator and belt are working like they should but the battery wont hold a charge. I took the battery to Sears (6 month old Diehard) and after a day and a half they said the battery is good. Now the car starts each time but the lights(inside and out) all flicker and when you press the gas they flicker more? After about 5 minutes the flickering stops. What could be the problem?
