2005 won't start, 15 stored codes HELP!

OK so I bought this truck from a friend today, got it for a great price and hope to fix it. Truck ran fine Monday night, wouldn't start Tuesday morning when he went to leave for work. There are 15 stored codes in the computer. I can tell you in the last year, he's replaced the transmission which was done at Toyota, 6 new Airtex coils, new plugs, new radiator, new thermostat and housing, new belt, new manifolds and cats, oil changed and air filter changed 2 months ago, possibly more but not sure at the moment. Truck has the 4.0 and has about 250K miles on it currently. I'm leaning towards one or both of the cam sensors causing most of this and causing the no start issue but I could be wrong. Any help would be greatly appreciated.

Stored codes are as follows
P0340
P0345
P0020
P0010
P0343
P0348
P0102
P0113
P0118
P0121
P0123
P0452
P2135
P0778
P2716
