Need some help.

I am having several problems with my 93 rx7. I have had troubles with the thermostat reading hot and then going right back down to normal once it gets hot. This happens during normal driving or sitting still with the car running for a couple minutes. Also, if I leave the car sitting for more than two days, I have a really hard time getting it to start, if it even will. When it does start, it smokes really bad for several minutes. When I turn it off, it smells of gas for a while. And from time to time it will leak coolant. I have not been able to get the car to start all week after hours of trying, it will turn over but will not start.

Any suggestions would be helpful
