I have been fighting this problem for about 2 weeks. First thing in the morning or if it sits for acouple hours the car fires right up. Now if it sits and idles and gets warm or if I drive it to work about 5 miles and shut the car off it wont start. It will try and start but, its like the battery is very low. Ive replaced the battery, the ground from the battery, the cable from the battery to the switch, the cable to the starter from the switch, checked the ground from the engine to the firewall with an ohms meter, and I rebuilt the starter. Any suggestions? thanks
