Possible fuel system issues (5 codes)- SVT

Car was having electrical system issues, those were solved by a new battery and the "Big 3" cable replacement. Car drove great for about 1 week, then I experienced some stumbling. I checked the fuel filter, it was dirty as all get out; so I replaced the fuel filter. She ran fine for about 2 weeks. Now I am having some weird fuel system (i guess) issue. The car has trouble starting, but cranks just fine. I open the hood and shake the wire attached to the fuel rail pressure sensor and cam position sensor and unplug/plug in the cam position sensor and the car starts, but has problems maintaining idle until warmed up. After the car is warm, and being driven; anything under 4k and the acceleration is HORRIBLE. Over 4k it SEEMS normal. Below are the 5 codes I am throwing, any help will be appreciated at this point.

P0193 - Fuel Rail Pressure Sensor A (frp-A) ckt - High Input
P0325 - Knock S1 ckt (B1)
P0340 - Camshaft Position (cmp) A ckt (B1 or single sensor)
P1380 - Camshaft position actuator ckt (B1)
P1504 - Idle Air Control (iac) ckt

Any Ideas?
