I have a 2002 2500 with a 6.0 and for the third time it has not stared. The first time it started 15 minutes later after doing nothing. The second time it started 5 hrs later after we got it off the towtruck and the 3rd time it has still not started. When you get in and put the key in everything is normal and when the key gets turned to the accessory position everything is normal, the lights come on on the dash, headlights, radio, everrything works fine. But when you try to crank the motor it does absolutely nothing. Not even a noise or a click or anything. After the second time i took it to two mechanics shops and they both were unable to find anything because the truck would not do anything wrong. They said it was not throwing any codes and they went over the keyless entry system and checked the battery, alternator, and the starter and everthing comes back good. They told me there is nothing i can do unless the truck is acting up while it is in the shop. Any Ideas
