60 series Detroit won’t start

Hook up DDCT and Check if you can connect to ECM If so then it will show you any faults while cranking .........If it doesnt connect to ecm you have either no power to ECM or a Dead ecm

 

Sorry, I missed this. Good either which is not most starting fluids anymore. Will combust on any cycle with the piston coming north a 1/4". It can bang off on wrong stroke even if valves are bent and stuffed into the head. It is so volatile it ignights with a bic lighter in the air. I wouldnt rely on it to diagnose my valve condition, or position.

Some of you guys need to learn what and how you are using stuff.
