Welcome to 2CarPros.
First, if the vehicle cut off while driving, I don't understand why the starter was replaced. Also, can you tell me where the smoke came from? It may have been the starter itself if you were trying for an extended time. As far as the it starting and then turning off when you try to drive it, it could be a few different issues.
First, will it continue to idle after starting of you don't put it in gear? Does it start and then just turn off? Have you ever had the fuel filter replaced? Does the check engine light stay on when the engine does run?
I am going to provide a few different checks for you. They may seem difficult, but if you follow the directions, you should be fine. Also, if you confirm a specific problem when testing, I did provide the directions for repair.
If the light stays on, there will be diagnostic trouble codes stored in the car's computer. You need to scan the computer to retrieve these codes. Here is a quick video showing how that is done.

I realize most people don't own a scanner, but often times a parts store will lend or rent one to you. If the light is staying on, try to get a scanner and do what is shown int the video.
Next, low fuel pressure ( a bad pump or plugged filter ) can cause this too. Here is a link that shows how to test fuel pressure:
https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator
Here are specific directions for testing fuel pressure for your vehicle. The attached pictures correlate with these directions.

Step 1
COMPONENT TESTS AND GENERAL DIAGNOSTICS
OPTIMA(TF/QF) 2015 G 2.4 GDI THETA II Engine Control / Fuel System
Fuel Pressure Test (Low pressure system)
1. Release the residual pressure in fuel line .
CAUTION:
When removing the fuel pump relay, a Diagnostic Trouble Code (DTC) may occur. Delete the code with the GDS after completion of "Release Residual Pressure in Fuel Line" work.
2. Install the Special Service Tool (SST).
(1)Disconnect the low pressure fuel feed tube from the low pressure inlet of high pressure fuel pump.
CAUTION:
There may be some residual pressure even after "Release Residual Pressure in Fuel Line" work, so cover the hose connection with a shop towel to prevent residual fuel from spilling out before disconnecting any fuel connection.
(2)Install the special service tool for measuring the fuel pressure in between the low fuel feed tube and the low pressure inlet of high pressure fuel pump (Refer to the figure below).
picture 1
3. Inspect fuel leakage on connections among the low fuel feed tube, the low pressure inlet of high pressure fuel pump, and the SST components with IG ON.
4. Measure Fuel Pressure.
(1)Start the engine and measure the fuel pressure at idle.
Fuel Pressure:
480 - 520 kPa (4.9 - 5.3 kgf/cm2, 69.6 - 75.4 psi)
NOTICE:
If the fuel pressure differs from the standard value, repair or replace the related part (Refer to the table below).
picture 2
(2)Stop the engine, and then check for the change in the fuel pressure gauge reading.
Standard Value:
The gauge reading should hold for about 5 minutes after the engine stops
NOTICE:
If the gauge reading should not be held, repair or replace the related part (Refer to the table below).
picture 3
(3)Turn the ignition switch OFF.
5. Release the residual pressure in fuel line .
CAUTION:
When removing the fuel pump relay, a Diagnostic Trouble Code (DTC) may occur. Delete the code with the GDS after completion of "Release Residual Pressure in Fuel Line" work.
6. Test End
(1)Remove the Special Service Tool (SST) from the low pressure fuel feed tube and the low pressure inlet of high pressure fuel pump.
(2)Connect the low pressure fuel feed tube and the low pressure inlet of high pressure fuel pump.
____________________________________________
If the fuel pump fails and needs replaced, here are the directions for replacement. The attached pictures correlate with the directions. If the pump pressure is within the manufacturer's specifications listed in the above directions, skip the next step and move to step 3.

Step 2
REPAIR PROCEDURES
OPTIMA(TF/QF) 2015 G 2.4 GDI THETA II Engine Control / Fuel System
Removal
[Type1 for TF]
1. Release the residual pressure in fuel line .
2. Remove the fuel pump service cover (A) in the trunk.
picture 4
3. Disconnect the fuel pump connector (A) and the fuel tank pressure sensor connector (B).
4. Disconnect the fuel feed tube quick connector (C).
5. Remove the fuel pump plate cover (D) after removing the bolts.
pic 5
6. Remove the fuel pump from the fuel tank.
picture 6
[Type2 for QF]
1. Release the residual pressure in fuel line .
2. Remove the fuel pump service cover (A) in the trunk.
picture 7
3. Disconnect the fuel pump connector (A) and the fuel tank pressure sensor connector (B).
4. Disconnect the fuel feed tube quick connector (C) and the vapor tube quick-connector (D).
5. Remove locking ring (E) by use the special service tool [SST No. : 09310-2S200].
picture 8
6. Disconnector the vapor tube quick-connector (A) at the fuel pump, and then remove the fuel pump from the fuel tank.

Installation
1. Installation is reverse of removal.
CAUTION:
Be careful of fuel pump direction (Refer to the groove in the fuel tank).
Fuel pump installation bolt :
2.0 - 2.9 N.m (0.2 - 0.3 kgf.m, 1.4 - 2.2 lb-ft)

Step 3
If fuel pressure is good, my next suspect is a faulty crankshaft position sensor. Take a look through this link and let me know if it mirrors what you are experiencing.
https://www.2carpros.com/articles/symptoms-of-a-bad-crankshaft-sensor
If it does, here is a link that shows in general how one is replaced.
https://www.2carpros.com/articles/crankshaft-angle-sensor-replacement
If the description in the symptoms link fit your problem, follow step 4. Keep in mind, the best way to check the sensor is using a live data scanner to see if the engine's RPM signal is lost when it stalls. If it does, the sensor is most likely bad or there is a wiring problem
Here are the directions specific to your vehicle for sensor replacement. Again, the attached pictures correlate with these directions.

Installation
CAUTION:
Install the component with the specified torques.
Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
CAUTION:
Apply the engine oil to the O-ring.
CAUTION:
Insert the sensor in the installation hole and be careful not to damage.
