Sounds like two different problems. The no start could be fuel or ignition related. The loss of coolant could be an external or internal leak, including a head gasket.
You would need to figure out if you are lacking spark or fuel pressure when it fails to start to proceed with testing.

93 seville sts runs great and then after driving wont star fot 30 min to an hr. any easy solutions?


If/when you do get it started, do you have to hold the petal to the floor or give it a lot of gas to 'clear' it up again? Does it smoke when you first start it up? If so, you might have a leaking injector (s), the o-rings allow pressure to push gas into cylinders when you shut down, flooding the cylinder-will cause hard starting. If this is not the case, consider a heat-sink kind of situation with the crank sensor-it gets hot with normal driving, and gets even hotter with heat-soak when shut down and changes electrical properties (specifically resistance) until it cools down again. change the crank sensor.

If you don't have any engine lights on, the first thing to replace would be the fuel filter. It is located under your car, probably about half way down. Just follow the gas line, and you'll find it.
