check and see if your thermostat is stuck open(top of engine block). depending where you live, water could be slushy or frozen in your engine.

It could be that the starter or solenoid is in a bind after the engine warms up. Metal expands and contracts with temperature. This is only a solution if it starts when cold which would be the first time it is started. Try starting it cold then shut it off before it gets hot then see if it will restart. If it won't start when hot maybe try replacing the starter. Hope that helps you out.

check for fuel pressure, should be around 50 psi. try getting someone to bang on the bottom of the gas tank while cranking, might get it going to determine if its the pump
Ask this question again. Is the question no blowing or blowing cold?
You should check the thermostat and the fuse for the heater.
On a 2009 Pontiac Montana, the block heater is typically located near the engine block, specifically on the driver's side, towards the front. It is a cord that plugs into a standard electrical outlet, making it easier to start the vehicle in cold weather by warming the engine. If you're having trouble locating it, check under the hood for a cable or plug that may be tucked away or secured to the engine.
The cold start injector valve on a 1988 Pontiac Fiero is located on the intake manifold, typically near the throttle body. It is designed to provide additional fuel to the engine during cold starts to assist with ignition. To access it, you may need to remove a few components around the intake manifold for better visibility and reach.
A bad relay switch could be the culprit if dash lights remain on after engine starts in a Toyota. Cold weather can also cause these lights to stay on after the engine starts.
Could be low coolant, stuck thermostat, bad heater control head (if climate control)
The time it takes for a vehicle to warm up in cold weather can vary depending on factors such as the engine size, type of fuel, and overall efficiency of the heating system. In this case, the Pontiac Montana may have a larger engine or a less efficient heating system compared to the 2000 Blazer, causing it to take longer to warm up in extremely cold temperatures like -30 degrees Celsius. Regular maintenance, such as checking the thermostat and ensuring proper engine performance, can help improve heating efficiency in cold weather.
Apparently when its hot it should be higher than the cold level I read this in my owners manuel .. not very helpful..
It could be sticky or worn valve parts.
The engine block heater cord on a 2008 Pontiac G5 is typically located near the front grille of the vehicle. It is often tucked behind or near the front bumper for easy access. The cord is usually a thick, insulated cable that can be plugged into a power source to keep the engine block warm in cold weather conditions, aiding in easier starts and reduced wear on the engine.
The #1 cause of cold air from the heater when the car is stopped, or the engine is idling, low engine coolant levels.
Check the engine coolant temprature sensor it may be sending the wrong signals to the ECU making the ECU think the engine is cold and overfueling the engine.
