2004 Mitsubishi Lancer OBD II codes

2004 mitsubishi Lancer 2.0l 2000cc
Ok I am having starting issues out of nowhere, I was thinking a fuel issue but I could be wrong. I have verified fuel flow from tank to fuel rail. I have detected signal to injectors via a noid light. I can get the car to start using starter fluid sprayed through the airbox where it promptly stalls out with a major shaking from the engine. I just bought a OBD II tester and came up with these results :

P0201 Injector Circuit / Open - Cylinder 1
P0202 Injector Circuit / Open - Cylinder 2
P0204 Injector Circuit / Open - Cylinder 4
P2228 Barometric Pressure Circuit Low Input
P0102 Mass Or Volume Air Flow A Circuit Low Input
P0113 Intake Air Temperature Sensor 1 Circuit High Input
P0335 Crankshaft Position Sensor A Circuit Malfunction
P0340 Camshaft Position Sensor A Circuit (Bank 1 or Single Sensor)

By now the battery is low from trying to start it up which might explain the low inputs. At the time of the diagnostic test, the car was not running, it was turning over at the time.
will this info from the scanner help break down the issue. As for example one unit not functioning causing a chain reaction bringing up the other codes?
perhaps a bad cam position sensor or something. I failed to mention the evening before this failing to start, I was driving in torrential t-storms and went through some deep puddles on the highway. Any help is really appreciated.
