No Spark Signal, Crank No Start

I checked the cam position sensor the plug connector was corroded I unplugged it bought a new one spliced it connected it, the truck used to turn on and stall at idle or stops, after I changed that Cam Position Sensor and the Cam Position Sensor connector, the truck would not turn over no more just crank, I checked for fire to the coils it receives power but no spark out the boot. I checked for voltage on the Cam Position sensor wires I installed and no volts displayed. What could be the issue? I also noticed that near the air conditioner compressor the Crankshaft Position sensor seems soaked in oil dirt or water not sure what else. Do you think this can be the PCM? Bad Wire? Or the Crank Shaft Sensor?
