Have you figured out if you are missing spark or fuel to make it stop running ?

I don't know the exact pressure but 55 psi sounds good to me. Most ordinary passenger cars run at about 2 bar with something like a 5 psi increase for acceleration. A pressure test isn't a lot of use on its own as it is possible it can provide the pressure when no demands are placed on the engine but not deliver the volume of fuel needed when demands are made. A peak pressure test and a flow test would ensure the fuel system is good. I am wondering if the egr valve is on the same side as the lean bank? Dodgy egr valves are a big cause of bad running.

Buy a two pack of turn signal bulbs. Change the front and rear left bulbs and try it out. If you're lucky, you're done and got away cheap. If not, start chasing electrons. Not an overly complicated circuit, the signal is quick flashing because you have an inoperative lamp.

Did you get your recalled ignition switch changed out at your Chevy dealer? Please cal them and check to see if it was done last year. If not, get it done (it's free) and have them give you the print-out of any fault codes they find. Get back with us.

Check neutral and park switches

It doesn't have one. To check the fluid you have to pull a plug from the passenger side of the transmission, by the CV shaft. Start the car and pull the plug. If fluid comes out, it is full. If not then add. The fill is the red cap on the top of the transmission.

if it changes when turning right or left it is a wheel bearing if noise does not change when turning try rotating tires from front to rear and see if it goes away as it may just be tire noise

Blow out the sprayer from outside. If it does not clear it get a new nozzle.

Transmissions are electronically controlled. If you put it in drive and it acts up it is because of transmission failure. It could be electronically or mechanically. Since you have an 09, I would guess it is electrical, unless you have had a transmission leak.

hook up a to the obd and comand the ecm to prime the fuel pump if it doesnt prime its the ecm providing wires and relays are good
