Start point
It's called Easy start. Follow the directions printed on the can
The starter drive, also sometimes called the bendix, needs to be replaced.
You start the engine in neutral.
If the timing is off by a few degrees the engine can start but will run rough. More than a few (depending on the engine) it will not start.

A diesel engine has no spark plugs. Because the air is so compressed and hot at the top of the stroke, the fuel ignites right away when it is injected. This is why a diesel engine is called a "Compression Ignition" engine and gasoline engines are called "Spark Ignition" engine. This also means that there are no ignition breakers, ignition coils, distributors and ignition wires to go bad. This allows diesel engines to start no matter if it is dry or rainy and wet. The immense compression creates the heat that ignites the fuel. On cold days a glow plug may be necessary to heat the combustion chamber enough to start the engine.
There is a school, I think in Texas, called UTI. Universal, Technical, Institute. Start there.
when the engine is hot the check engine light came on and the fan(is ok) don't start
On an interference engine you can have internal engine damage when you attempt to start it. On a noninterference engine it may not start or it may backfire, or miss, if it does start.
That engine needs fuel, compression and spark to start and run. You are missing one of those.
That is called condensation. When you start the engine the exhaust system/pipes are cold. When the heat from the engine exhaust passes through the exhaust it makes it sweat. That is normal.
