Answer 1

Technician B who says that low compression on a single cylinder will affect the engine’s cranking sound

Step-by-step explanation:

if you have low compression in one cylinder, the engine will start but you'll likely experience misfires and your vehicle will run roughly.

It's only when you have no compression at all that the engine will not start.

The technician that said that low compression on a single cylinder will affect the engine’s cranking sound is correct.
