Thank you for your input. I am pretty sure I only removed 2 ground straps during the head gasket repair. One over the left exhaust side of the head near engine shock mount (shown in green in the attachment) and the other from the driver side of the head near the cam sensor (EG shown in red). I will check my fuses and grounds tonight. Also, is there a common wire harness/ground path to search for that would throw the P0010, P0748, P0778 and P2716 codes. I forgot to mention that these codes come up every time with the key in the "ON" psoition. Don't even need to crank the starter.
