"it's not head gasket because engine oil good"
It is entirely possible for an engine to have a breached head gasket, even if there is no evidence of coolant in the motor oil. Have a good mechanic do a compression test and also check for the presence of combustion gasses in the oil.
Test for combustion gasses in the antifreeze. That would tell if there is exhaust gasses getting into the antifreeze.
It sounds like your shop is doing all the right things. As posted above, it could still be a head gasket problem, and testing for combustion gasses in the coolant is a very good idea. This would be especially likely if the car overheated for some other reason first, like a radiator fan failed, or b/c of a coolant leak and low coolant, or the water pump failed. The first overheating often weakens the head gasket and after a while it eventually fails. Do you notice any air bubbles rising up in the radiator with the engine idling and the radiator cap removed? That also would indicate a head gasket leak.
Other ideas? Low coolant level, an air bubble lodged in the cooling system somewhere, or a faulty radiator cap could cause this symptom. Make sure the cooling system doesn’t leak and has been air-bled using the factory service manual’s procedure, and ask your shop to pressure test the cooling system, including the radiator cap. Those are all fairly inexpensive procedures. You might first want to just buy a new radiator cap if it is an old one. They tend to go bad after years of use.
And thing is car not staring now ,crank rotating but won’t start ,I will be in a big trouble now .thankyou very much for all suggestions. I will do it .
Pull some spark plugs, they may be fouled by antifreeze.
