I got a 2500 6.7 2014 and I blew an idler Pully which caused the belt to fall off and fray. I replaced the pulley and belt but I have a red lighting bolt (service electronic throttle control) that is on steady and the truck has problems wanting to start. Normally it would start first crank now takes about 4 and It won’t always start. Especially if you fire it up and shut it down right away guaranteed not to start for an hour or so. This all happens when the idler pully blew. What do I need to fix this or how?
