The location is number 1 in the picture.

neutral safety switches are for older vehicles, your impala has an IMS (internal mode switch) which is inside the transmission

no key? use a portable starter pack that plugs into a power port lighter etc

Could be gearbox, could be clutch thrust bearing could be almost anything to do with the transmission.

Crankshaft Position (CKP) Sensor B (LA1) Middle rear of the engine, below the exhaust manifold Turn the steering wheel fully to the left. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information. Remove the right front wheel. Refer to Tire and Wheel Removal and Installation in Tires and Wheels. Disconnect the crankshaft position (CKP) sensor electrical connector. Remove the CKP sensor bolt. Remove the CKP sensor. Inspect for wear, cracks, or leakage if the sensor is not being replaced. • Crankshaft position (CKP) sensors The CKP sensor B is a variable reluctance sensor. The magnetic field of the sensor is altered by a crankshaft mounted reluctor wheel that has seven machined slots, six of which are equally spaced 60 degrees apart. The seventh slot is spaced 10 degrees after one of the 60 degree slots. This sensor provides the ignition control module (ICM) with 7X signals, or seven pulses for each revolution of the crankshaft. The pulse from the 10 degree slot is known as the sync pulse. Both of the sensor circuits are connected to the ignition control module (ICM). A signal converter within the ICM produces digital 3X output pulse to the powertrain control module (PCM), the 3X reference is known as the low resolution engine speed signal. The CKP sensor A contains a hall-effect switch. A hall-effect switch is a solid state switching device that produces a digital ON/OFF pulse when a rotating element passes between the sensor tip and a magnet. This rotating element is called an interrupter ring or blade. In this case the interrupter ring has 24 evenly spaced blades and windows and is part of the crankshaft damper assembly. This sensor provides the PCM with 24X signals, or 24 identical pulses per crankshaft revolution. The 24X signal is used for enhanced smoothness and idle stability at a lower calibrated RPM. The PCM supplies the sensor with a 12-volt reference, low reference, and signal circuit.

Use PTFE tape and fix hand tight. Check for leaks and tighten with care if needed.Steel switch and Aluminium case, not good!

Backside of the engine before the catalytic converter

either switch or motor is stuck or bad

sounds like a blown fuse

Hooking up a professional type scan tool an doing a full computer system scan would be the thing to do . This would check for codes in all the modules on the vehicle , BCM , PCM / ECM , ABS , Air bag, instrument cluster , radio , HVAC - heating an A/C etc... Could have a module bring down the serial data network . Do you know what that is (data network) ? You should also know what happens when you turn the key to start . Also checking the 5 volt reference circuit from the PCM/ECM .In modern vehicle design, 5-volt reference signals/circuits are a key aspect of vehicle command and control. As summarized by Gary Goms, the 5-volt reference signal typically "flows through a sensor containing a resistance that varies according to changes in temperature, pressure or position. https://cloreautomotive.com/blog/troubleshooting-5v-reference-circuits/#:~:text=In%20modern%20vehicle%20design%2C%205-volt%20reference%20signals%2Fcircuits%20are,according%20to%20changes%20in%20temperature%2C%20pressure%20or%20position. Data Link Connector (DLC) The DLC is a standardized 16 way connector located below the instrument panel and close to the steering column. Both the connector design and location are dictated by industry wide agreement to follow SAE J1962 standards. All DLCs are required to provide a power supply, hot at all times, to Pin 16. This circuit is used to power the scan tool. All DLCs provide a power ground at Pin 4 and a clean signal ground at Pin 5. The class 2 serial data communications circuit is provided at Pin 2 of the DLC. Class 2 Serial Data Link The class 2 serial data link allows the following modules to communicate and share data with each other: • Auxiliary Power Drop Connector • Body Control Module (BCM) • Digital Radio Receiver (U2K or U2L) • Driver Information Center (DIC) • Electronic Brake Control Module (EBCM) • Instrument Panel Cluster (IPC) • OnStar Module (UE1) • Powertrain Control Module (PCM) • Radio • Inflatable Restraint Sensing and Diagnostic Module (SDM) The class 2 serial data link allows a scan tool to communicate with the above modules for diagnostic and testing purposes.

do those two cylinders share the same coil??

I tidied up your question a bit into what I think you were trying to say. Sentence run-on, with no commas, can be a problem in understanding the question, so I made about 5 sentences out of your one. :>D You said you 'tried to do a reset'. How did you do that, did you disconnect the battery? How long for? Was the key in the ignition when you reconnected? Most of your issues are due to the anti-theft system being activated, so I will put my link to fixing that at the bottom. Regarding the transmission slipping and overheating, it sounds like you are low on transmission fluid. This would cause slipping and overheating. Resetting the Anti-Theft System. https://www.fixya.com/cars/r26859529-resetting_vehicle_anti_theft_system Click Comment, below my post and let me known how you get on.

unscrew or drill out pop rivets on hinge and replace

Do you have access to a scantool or code reader? Many things can cause a crank no start condition, we need to narrow down what direction to go.

Check fuse first. If ok then likely speed control module or blower motor itself is faulty.

Fuels, petrol or diesel, are known as hydrocarbon (hydrogen and carbon) fuels and so when burned in air (oxygen) one of the resulting products is a considerable amount of H2O or water. Mostly this is expelled through the exhaust as vapour but at certain times, such as when the air is cold and dry and the engine and exhaust system is cool, the vapor will condense and emerge as steam and water droplets. When a vehicle has lots of short journeys, the exhaust can become waterlogged where the silencers can retain a great deal of water and are likely to be spitting water droplets almost continuously. Often the sound at the tailpipe will be more harsh than usual. Some manufacturers have a small hole at the lowest point of a silencer to allow surplus water to drain away and sometimes a mechanic will drill a hole... Spitting water and emitting steam is often seen as a sign of a failing head gasket and the confusion is understandable as it is a natural function and could be a symptom of head gasket trouble but it is a symptom that should not warrant much attention in isolation - clearly if a failing head gasket is the source of water spitting from the tailpipe, the coolant level will be mysteriously falling without obvious leakage and often the engine will suffer a misfire on starting...

Start the vehicle? Cycle the key a few times to prime the system and it should start. The electric fuel pump turns on as soon as the key is turned to the run/on position.

which engine does the vehicle have?

Chevy has 3 different antitheft systems. What year is your Impala?
