One of the first things you need to do is retrieve the trouble codes.
My bet is that you have some injector circuit codes for the even bank. The thing about these trucks is that one injector fault will kill the whole bank. These codes include:

Shorted injector circuit (either in the wiring or the injector)
P1262 (cyl. 2)
P1264 (4)......
P1266
P1268

Open injector circuit (either in the wiring or injector)
P1272
P1274
P1276
P1278

High side faults
P1292 Shorted
P1294 Open

Don't forget that there are connectors all over the place. The IDM connector, the engine harness connector (the big square one above the left valve cover), the ones at the valve cover gasket (external and internal), and one at each injector.

Good luck!
