Car wont start

When I try to start nothing no crank. If I use the purple wire across to b+ it tries to start but doesn't. The key sticks in ignition gas gauge and temp gauges do not work. Service anti theft. Stability system comes on the dash screen. When all this started I pulled into parking. Lot and parked on downhill slope and got to close to curb. When I let go of brake it jammed the car in park and key would not release. Also I had the recall done but they could not start and I was to broke to do diagnosis. I am on fixed social security and cannot afford dealership mechanics. The car has been a lawn ornament for nine to ten months. Bought a new heavy duty battery. Not the problem. Please advise. Thank you so much.
