OBD codes 14 and 34, Engine turns over fine, but not a hint of firing?

I would replace the MAF and coolant sensors here is what is said about the codes:

OBD Code 14: This code indicates a problem with the Engine Coolant Temperature (ECT) sensor or circuit. The ECT sensor measures the temperature of the engine coolant and sends this information to the engine control module (ECM). A faulty ECT sensor or a wiring issue in the circuit can trigger this code. It's important to address this issue as incorrect temperature readings can affect fuel delivery and engine performance.

OBD Code 34: This code indicates a problem with the Mass Air Flow (MAF) sensor or circuit. The MAF sensor measures the amount of air entering the engine and sends this information to the ECM to calculate the appropriate fuel delivery. A malfunctioning MAF sensor or a problem in the circuit can trigger this code. Issues with the MAF sensor can result in poor fuel economy, rough idle, and decreased engine performance.

To diagnose and resolve these issues, it is recommended to perform the following steps:

Inspect the wiring and connectors associated with the ECT sensor and MAF sensor. Look for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring or connectors.

Check the ECT sensor and MAF sensor using a multimeter or follow the manufacturer's recommended procedure. Ensure that they are functioning correctly and providing accurate readings.

If necessary, replace the ECT sensor or MAF sensor with a new one. Make sure to use compatible parts for your specific vehicle model and year.

After making any repairs or replacements, clear the OBD codes using an OBD scanner or by disconnecting the vehicle's battery for a few minutes. This will reset the ECM and allow it to recheck the system.

Please let us know what happens.

Thank you.
