hard start/long crank
hey guys, my 07 6.0 has been taking longer and longer to start lately.today it started after a long crank and ran great to the jobsite. about 15 minutes later i got back in and tried startin but it just cranked and cranked. no start. checked all fuses and relays. all were good. finally it started. i got to next jobsite turned off, then 20 minutes later started fine and drove to a supply house 15 miles away. thats where it wouldnt start for 45 minutes. i tested batteries and read 12.5 on both independantly. tested FICM and read 48v wit key on/engine off and 48v while cranking... anybody got ideas why it would start when motor is cold and not start while hot? thanks
