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.
try testing icm free at autozone must be off
car to test
ck coolant temp sensor
ignition modual
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.
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)
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 #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.
Mine stays at the first quarter, up from cold. I would add more coolant if the gauge is unstably going up and down at different speed. I think you may have a slow to open or sticky thermostat if you feel nervous as your engine warms up, and the temperature needle climbs and climbs, and starts to smell like roast duck with penzoil au jus...
This engine will have seven injectors. 6 are the running injectors and there is a "Cold Start" injector.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
Get a K&N cold air inflow system and Magna flow exhaust. That will get you more HP!
