No spark no fuel

I just put a new timing chain in my vehicle. Before I did so, it ran. Just with bad timing. I have the engine put back together with new oil in it. Have not put the serpentine belt back on or the radiator as I feel this is not my problem. Since I have the engine put back together, before I went any further I wanted to see if it would run for a few seconds. But I am getting no power to the coils and no fuel. I scanned the computer and it gave me a p168 code. Ignition one switch circuit two. I checked voltage at ignition and it is all good. I checked fuses and relays. They are all good. I made sure all sensors and computers are hooked back up properly. But still no luck getting spark or fuel. And my security light does not flash, so I do not believe the pass lock has been activated. Serious help needed.
