That's where I am at right now. Hopefully I'll have time to mess with it some more later.

Oh yea, the starter seems to turn the engine fairly slow. Battery is good and I have even hooked up jumper cables to give it some more juice but still turns over slow
I would suggest checking the battery voltage first when you are cranking. If the battery voltage is below 10.5 volts it will not run properly.


P0113 - IAT Sensor Circuit High Input Conditions:

Possible Causes:

1. IAT Sensor signal circuit shorted to VREF 5 volts
2. IAT Sensor signal circuit is open, or the ground circuit is open
3. IAT Sensor is damaged or it has failed
4. PCM has failed

P0113 can also be caused by a vacuum leak. Check all vacuum hoses. Check to make sure your PCV valve hose is not cracked or leaking and your PCV valve is working properly. They might have pulled a vacuum hose cracking it when it was being checked for smog.


P0522 - Engine Oil Pressure Sensor voltage low:

Possible Causes:

1. 5 volt supply circuit is open or is shorted to ground
2. Oil pressure Sensor signal circuit is shorted to ground or to sensor ground
3. Oil pressure Sensor is damaged or has failed
4. PCM has failed

Your Camshaft or Crankshaft sensor (5 volt line) might be shorting to ground. I would suggest you remove the wire going to the camshaft sensor and try starting the engine without the wire connected.


P0622 - Generator Field Not Switching

Possible causes:

1. Battery charge
2. Faulty Generator
3. Generator harness is open or shorted
4. Generator circuit poor electrical connection
5. Faulty ECM
