Diesel engines are compression combustion engines, versus gasoline engines are ignition combustion engines that use a spark plug to ignite the fuel in the combustion chamber. diesel engines squeeze and compress air so much forcing the air molecules to come together so close that they rub and vibrate erratically causing so much friction that they get so hot that they ignite the fuel in the combustion chamber. the sequence of a diesel engine is suck, squeeze, bang, blow. lol anyways, they suck in fresh air and fuel, the piston then rises squeezing the air until hot enough to ignite the air fuel mixture causing an explosion, there's the bang. This forces the piston back down while turning the cam shaft putting power to the crank, on the pistons way back to the head it opens the exhaust valve and blows the burnt air fuel mixture out the exhaust. some diesels don't like to start when they're cold so plugging the exhaust and sealing it adds a little more compression to the system therefore heating the air just enough sometimes to help the engine start, and Wala.... there you have it. The reason plugging the exhaust on a diesel engine sometimes helps it start. I spent 6 years active duty Army as a 30 level Deisel mechanic and I've used this same exact method to start hundreds of military vehicles. if anyone ever tells you that it won't work, they're probably the know it all douche bag type and only say #### like that because they're committed to being a loser and will never swallow their gay pride like they swallow wieners and actually try it themselves because then they'd have to admit they were wrong and dip #### snowflakes like that would rather cut off a finger than have to admit to being wrong about anything. You can bet your ### it works. next time you find yourself with a cold natured diesel engine of any kind... just wad a big shop towel up the exhaust pipe and pack it in until its sealed pretty good then hold it in there with all your might and have someone crank on it and see if you don't get a face full of smoke from when that puppy fires up.
No start condition - cover the exhaust with a rag and it starts
