How long does a ym240 diesel engine run?
I started my YM240 (24 hp diesel) this spring and it runs absolutely fine for about 1/2 hour – plenty of power under load, no smoke, no blowby, everything seems normal. Then, after about 1/2 hour it starts losing power and in a period of about 3-4 minutes it loses so much power that it can’t climb a small grade unless I drop it into 1st gear.
Why does my diesel engine start then quit?
You don’t say if it runs for 10mins, 10 seconds etc etc, makes a difference but if it starts and runs good then quits in seconds, you’re probably into a safety feature designed to protect the engine. If it starts and runs for several minutes theyn probably a fuel flow issue, filter, pump, vent, squished fuel line etc.

When do you need a new PMD for a diesel engine?
Simply put, if your check engine light is not on and you experience stalling, it is a 95+ percent certainty that you need a new PMD. If your check engine light is on, you need to get your codes checked. Auto Zone and others will do this for free. If you ONLY have codes P1216, P1217, 35, 36 or any combination of those, you need just the PMD.
