To diagnose the issue with your 1993 Toyota Corolla DX, here's a step-by-step approach:
1. **Check for Diagnostic Trouble Codes (DTCs)**: Use an OBD1 scanner to check for any stored codes that could indicate what the problem is.
2. **Inspect the Fuel System**:
- Listen for the fuel pump to ensure it's operating when you turn the key to the "ON" position.
- Check the fuel filter for blockages.
3. **Inspect the Ignition System**:
- Check the condition of the spark plugs.
- Inspect the ignition wires and coil for damage or wear.
4. **Air Intake System Check**:
- Replace or clean a dirty air filter.
- Inspect the mass airflow sensor and clean it if necessary.
5. **Idle Air Control Valve (IACV)**:
- Clean the IACV if it’s dirty or replace it if faulty.
6. **Check Sensors and Electrical Connections**:
- Inspect the crankshaft and camshaft position sensors.
- Check all electrical connections for corrosion or damage.
7. **Visual Inspection**:
- Look for any obvious signs of wear or damage on vacuum hoses and electrical wiring.

Several car issues can cause your vehicle to stall or die shortly after starting. Some common reasons include:
1. Fuel Delivery Problems: Issues with the fuel pump, clogged fuel filter, or fuel injectors can result in inadequate fuel delivery.
2. Ignition System Issues: Faulty spark plugs, ignition coils, or distributor components can lead to a lack of spark and engine stalling.
3. Air Intake Problems: A clogged air filter or problems with the mass airflow sensor can disrupt the air-fuel mixture.
4. Vacuum Leaks: Cracked or disconnected vacuum hoses, or intake gasket issues, can cause stalling.
5. Sensor Malfunctions: Malfunctioning sensors, such as the crankshaft position sensor or throttle position sensor, can disrupt engine operation.
6. Electrical Problems: Wiring issues, damaged relays, or a weak battery can affect engine performance.
7. Exhaust System Blockage: A clogged catalytic converter can restrict exhaust flow, leading to stalling.
8. Overheating: Rapid engine overheating can trigger an automatic shutdown for safety.
9. Idle Air Control Valve: A faulty idle air control valve may not maintain proper idling speed.

Hi there,
There are four most possible causes of your problem. Check this out:
1. A dirty mass air flow sensor. A clogged and contaminated MAF sensor can cause incorrect fuel trim will cause immediate stalling of the engine.
2. Defective fuel pump. A faulty fuel pump may not maintain adequate fuel pressure once the engine is running causing it to die shortly just after running for a few minutes.
3. Clogged fuel filter. A restricted fuel filter would not sustain continuous supply of fuel to the fuel rail and cause the engine to stall.
4. A faulty idle air control valve. If it sticks or fails, the engine may be unable to maintain idle RPM after starting and stall out.
I hope this helps!
