What modifications can be done to make a Mazda RX-8 start in the winter?

Answer 1

What causes the car not to start in winter usually is that you can not crank it then shut if off immediatly. This car has a rotory motor. In the winter the ecm tells it to send more fuel so the car will crank. If u cut the engine off before the car is at normal operating temp the engine is still full of fuel, it fouls out the spark plugs and the next time u go to crank the car it will not crank. So never turn the car off when the engine is cold. For instance dont go crank the car back it out of drive to let someone out and then just cut it off let it run till it is warm then cut it off. If u have done this there is a starting procedure that usually works, but not always. Press the accelerator to the floor and try to crank the car for one min. If it does not crank in one min let is sit a while then go back and reapeat the procedure until it cranks. Again, stopping and letting it sit after one min. Once the car cranks let it run till it is warm, and at normal operating temp. Cranking the car when its cold and cutting it off before its warm can seriously damage it and cost lots in repairs. Never i repeat never do this. Always, make sure the car is warm before u cut it off.
