How do you prevent the engine starting while preforming compression test?
Truck is private sale, don't want to pull all the glow plugs out. Owner is also allowing me to use AutoEnginuity.
Hoping it its a UVC gasket or harness.
If you don't want to pull the glowplugs then you won't be accomplishing a compression test. They're not bad. And you can unplug the injectors too. Or find a fuse. if you want to do it that way. (DON'T RECOMMEND IT) Turn it over by hand. Not bad to do either.
