If the car does start when warm it will rev between 250 1800 rpm erratically usually shutting itself off and then will begin to idle normally after about 10 15 seconds. If the injectors are continuously dumping fuel when you turn the key before you crank its getting a noisy tach signal for some reason it wont do this if you reset the system on the first start up but every time after it will flood the motor.

Fitech wont start when hot. Press ok this will upload the setting. Go to main menu 6 go efi pro tuning go to 12 fuel pump control then 7 pwm low flow enter 40. You want the counts to be 3 10 fully warmed up in park or neutral. The default is for running the in tank or in line pump. Most likely you will have to adjust the idle screw to get the iac counts in range for it to start and run with no throttle. Check the rpms on the handheld to make sure it doesnt think its running before you crank it.
I am not running timing control i am getting good tach signal i have adjusted cranking fuel prime and cranking iac without any improvement. Since you are running the fcc you need to change the pwm low flow to 40.
