Figure this one out. It's weird!!
OK about a year ago my wife was on a trip with the truck a couple hundred miles away. She gives me a call one morning says the truck won;t start. Just cranks. So i tell her over the phone how to read the codes with the livewire. Nothing out of the ordinary. Typical tuner set codes. Like a KAM error code. Not sure what the number is but it has been on my truck since the SCT install. Anyway i get her to reprogram the truck to stock. She turns the key and it fires right up. Good i'll check it out when she gets home. She comes home i find nothing obviously wrong. Reprogram it with a custom tune. So i keep driving it thinking it will happen again. It doesn't until just now. Cranks fine but no start. Check codes and there is a p2614 cam sensor circuit open. (i think). Anyway reset codes and crank again. No codes this time. Instead of reprograming it to stock again like the last time i pull the battery wires and let it sit for about 5 mins. Put the cables on and it fires right up. Runs fine again???
Does anyone know what the problem is? Bad PCM? Bad FICM? is what i'm; thinking as it runs and starts fine after a reset. But i don't want it to totally quit on a trip somewhere.
Truck is a late build 2004. It has a livewire running looney tune and a tow tune regularly, straight pipe, and an airaid intake.
