2008 DODGE SPRINTER 2500 Engine Problems

VEHICLE WAS PARKED IN HOSPITAL PARKING LOT FOR ABOUT 6 HOURS. LEFT HOSPITAL AND WHILE TRYING TO START VEHICLE THE DASHBOARD INFORMATION CENTER INDICATED A NO START CONDITION. THE ENGINE WOULD NOT ATTEMPT TO CRANK. THINKING MY KEY WAS FAULTY, I TRIED MY WIFE'S KEY. SAME RESULT. NO CRANK. DASHBOARD DISPLAYED "START ERROR". AN ATTACHED DEVICE BY GARMIN THAT READS THE COMPUTER BUS AND COMMUNICATES TO THE GARMIN GPS HAD NO ILLUMINATION OF IT'S COMMUNICATIONS ESTABLISHED CONFIDENCE LIGHT.. SINCE THE VEHICLE WAS COLD I ACTIVATED THE AUXILLARY HEATER FOR WARRANTY. MY WIFE AND I SAT THERE FOR 15 MINUTES MAKING PHONE CALLS AND TRYING TO GET HELP. THE CABIN HAD WARMED UP SOME AND I TRIED TO START THE VEHICLE AGAIN. I WAS SUCCESSFUL. IN TRYING TO RESEARCH THIS PROBLEM ON THE SPRINTER USER FORUMS, I FOUND REFERENCE TO A SCREEM MODULE HAVING TO DO WITH VEHICLE SECURITY. OTHER USERS...
