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.

OBD Code 34: This code indicates a problem with the Mass Air Flow (MAF) sensor or circuit.

Please let us know what happens.

Thanks for your input. I will update you with the results.

Thank you.
