Ram 2500 5.9l starting issue
I have a client with an 02 2500 with the 5.9l. the issue We are having is the motor will not start on the first try. It "wants" to turn a few times, then turn the key to the off position, then it will start right up. I've done a full tune up and replaced both O2 sensors. Most everything in the throttle body has been cleaned, and once it is running it runs great. This also happens mostly when cold. Any ideas will be appreciated.
