In the hot condition when you turn key do you hear fuel pump prime? I would check that first as mine has been acting weird since the vats was disabled and when I pull my pcm fuse my fuel pump doesnt want to get signal for a while even with security light off.

Ok hears what we found tonight massive miss number 5 running rich as all get out icm tested 6 times got slower as we went along ran for bout 10 mins died can smell gas wont start smells flooded so gonna change plugs and pull o2s to check them seems to b runnin rich when it is runnin heck idk im over it
If the ICM is shorting internally with heat soak, or creating an open circuit, it should set codes and those codes DO NOT turn on the SES light. Have you scanned it for codes?
