Ok guys need some help. I have a 2005 chevy its stock besides intake and exhaust i recently purchased an autocal and efi live from atp and got it installed on the truck. First time i went to fire it up after doing a full flash the truck idled at 850 to 900 rpms. Also on my bullydog gauge and autocal it says the coolant temo is -40. I have since flashed the truck back to stock and checked all connections which appear to be good. Replaced coolant sensor with no luck. I check voltage at the coolant sensor plug with truck running and it is 0. Truck also has loud injector rattle and delayed throttle response. I am kind of confused on whats going on and why in am not getting power to the plug. Any help is appreciated. Thanks!
