If it was running before you replace the thermostat, check for ground wire's in the area you were working at, very important on imports.Other will still run, not imports.

The easiest way to rule out a fuel starvation problem is to remove the rubber air tube between the throttle body and the air box, manually open the throttle body valve and spray a short burst of stating fluid into it. Quickly release the valve, and attempt to start the car. If it starts and runs briefly then you are not getting fuel.
Hot air is dependent on the coolant temperature and the heater core.
There are several things that can cause your problem. The easiest to
check is the coolant level in the radiator\reservoir. There must be
enough coolant to flow freely between the engine and the heater core.
The next is the thermostat. If the thermostat is not closing it would
prevent the the coolant from reaching a high enough temperature to
allow for hot air. The thermostat is not expensive or difficult to
replace. The third thing is a blockage in the heater core. Flush the
coolant system properly can sometimes take care of this. If it does not
the only alternative is a new heater core. Hope this helps.
If it ran out of water and you filled it up just before the problem started then their may be air in the system so will need bleading. If that's not the problem then could be a sticking thermostat. Vheck these first and let me know if you need further help I can advise further. Cheer's
check the fuel filter and the hi tension wire and the distribution cap and also the battery terminal make sure it is fix and check the battery if still in good shape.
VSS or vehicle speed sensor aka cam sensor or crank position sensor. Test the battery and alternator. You should also check for blown fuses, bad wires and grounds on a car as old as yours. If you find it's getting spark and fuel after further testing, check the timing belt. It could have slipped or broke even if it was changed recently so either pull off the cover or at least do a compression test.
your throttle body is dirty and needs to be cleaned- also, you might want to check the spring and the various parts on the throttle itself for wear and tear.
the intake for air and the flutter wing could also be hanging up inside the air intake
