I been having problems with it overheating and the heat went out and i was going to get the radiator flushed to fix it but the next day when i tried to start it it would not start, everything else comes on , i have a new battery so i dont know whats wrong with it. when i turn it over to start it , it tries to run , it makes a burping sound from the back and also shakes a little

The heat going out was probably due to low coolant, which is probably going into your cylinders.
Check your coolant level.
