i have an 08 caliber rt and it has an extended crank when cold. in the morning, after it sits all night, there is an extended crank. it only happens when it sits and its cold out. my local dodge shop says it is either the computer or the fuel pump. they say they have to test it while the issue is occurring so i can either pick it up and wait for it to happen or let it stay there. any suggestions on how they should test this, should they call the help line and get approval to throw a part at it under warranty.
