ANOTHER UPDATE: Truck died after changing that CPS wouldnt start...nothing. Now Ive put in a new IDM and unplugged the batteries just incase it needed to reread. Truck still wont start. Acts like it wants to but wont and there is a small tick what sounds like is coming from under the valve covers...really not sure if thats where its comin from but theres an update....any help would be greatly appreciated. Thanks
