As I do not have this model of truck I can only assume that there is a loose wire someplace along the way. The relay that you speak of may control the DPC module.
This may be a loose battery cable or perhaps a bad ground someplace. Check all the heavy gauge wires from the battery to ground and also to the starter that they are tight and have good contacts. As stated I am not certain how your truck is configured under the hood but there will be some means of getting the power to the "accessories" of the vehicle. A plug, or some such thing that will attached to the POS + side of the battery.
