Replaced water pump and right side cylinder head and now car won't start

I replaced the crankshaft sensor, and by doing the ignition trick of on and off, I get the following diagnostic codes. P0340 ( camshaft position sensor ), P1388 ( Auto shutdown (ASD) ), P0622 ( Alternator field improper switching ), P1289 ( Mamifold tune valve solenoid circuit ), P1282 fuel pump relay control circuit. I bought another camshaft position sensor, but haven't replaced it yet, because for some reason I don't feel that is the source of not starting. This car has the 2.7l engine, and turns over easily, and will act like it is trying to start when I first turn on the ignition, but then just turns over and over. If I leave the upper manifold off, and try starting I do get flames up through the ports.
I do remember there was a ground wire bolted to the right side head, on the transmission end, but I have looked and looked and for some reason I cannot find the wire with the eyelet to bolt back to the head. I don't know if not having this ground wire attached could be the problem. I don't know what the ground wire came from. I am a 60 year old amateur mechanic, and this is the first time I have ever replaced a head, but other than that, I am pretty confident about most of the basics. I tripled checked the position of the timing chain, so that all the marks on the camshafts and crankshaft were properly lined up with the marks on the chain.
