Hello. My name is tan.

The over heat alarm is obvious over heat. This will be water pump failure or thermostats.

As for the engine not starting that could be many things. We must start with a spark and conmpression test. The compression must be 100 + psi with no more than 10% difference between cylinders. Then the spark must jump a 7/16" gap on a spark gap tester.

You could have loss of compression in more than one cylinder, fuel starvation or no spark.

Can you do these checks and post back with findings?
