Every once in a while (about once a month) I get in my car (1994 Mark VIII) after it sits for 8+ hours and it has trouble starting. It will crank and crank and crank until i have almost killed the battery. Sometimes it takes 5 minutes of actual cranking before the vehicle will start. It sounds like it is not getting fuel, but fuel problems usually have a smell, don't they? Then all of a sudden it will just fire up like nothing is wrong! I can turn the car off and it will start right up with no problems at all! Anybody have this problem?? Any solutions? Is it a sensor or something? HELLLPP!!
