P0013 & P0017 codes & AC not working (also--gas leak)

This car has been giving me hell for the last month-ish.

Last summer my check engine light came on with a P0013 and P0014 code. My dad replaced the clutch in my 2009 Pontiac G5 (currently 87,000 miles) and figured we could wait to correct the camshaft code. At the end of last summer, my AC also stopped blowing cold air. P0014 code is not longing showing but now a P0017 (ECT sensor circuit low voltage) is.

We figured it just needed recharged but the AC compressor wasn't working. Replaced AC compressor, when it's jumped it starts but doesn't automatically run. Tried replacing internal switch and partially traced wires. Half of the relay has power and the other half doesn't. Changing the relay, internal switch, and even reprogramming the ECM didn't fix it. I have to try to start the car twice before it fires up.

Blinkers don't automatically turn off even though bulbs are good.

Fuel pump was replaced Friday under warranty as a "special advisory" when I took it to the dealership to program the ECM.

Now vehicle is dying at stop signs/lights even with the clutch in and didn't start back up yesterday after getting gas. My mechanic "shortcut-ted" the ECM out of the AC wire path but when he puts it back the AC crank (?) doesn't kick on.

Any ideas for the AC or codes? I have read I should do a test with a multimeter to find out the power going to the OCV which will determine if the camshaft sensor is out or not. My thought is some of the wires are probably bad since there is so much going on at once but I thought I would get an educated opinion before buying a ton of sensors or tracing wires...

the sensors are a common problem and should be replaced and are not difficult to do. The compressor wont run if there is no gas so you have to jump it to get the initial pressure.
