Okay Hot and Cold No Start-Lets try looking for a spark at each plug wires while the engine is being crank over-Do you have spark? You need to answer

there is spark.the thing I dont under stand is that if I keep a sun reflector in the window and the windows down and the dash stays cool in temp. the car will start.but if it gets to cold it won't.so is there some type of sensor in the dash or something that it could be?

Did you get the spark on all the wires and is it a snapping blue spark-not yellowish. Okay we got spark, now its time to look for fuel- 3x for 5sec interval crank engine over-start or no start remove spark plugs is it wet with fuel.You need to answer. Check the circuit opening and EFI main relay-make sure its in there tight. If you know how to test it do so-this two has to work-its dealing with the sensors and the fuel injection system.also check the EFI and Ignition fuse. Note:Give me a little background of your mechanical and electrical abilities you can do. Do you have a digital multimeter?
