Car will not start.....HELP!!
 

I am having a problem with my 2007 IS 250.My car will not start. It is not the battery. I have had it tested, I havedisconnected it, I have tried jumping it. Headlights come on, brake lights comeon when pedal depressed, and interior lights come on. It is not the key FOBbattery either. The car is still able to be unlocked, locked, alarm activatedand trunk opened with it with no issues. When I depress the brake pedal thegreen indicator light on the start button does not come on, however"ENGINE START/STOP" on the button is illuminated. Dashboard light donot come on. Accessory mode does not come on. Engine doesn't turn over, noclicking noises, nothing at all. The door open indicator light on the dash constantlystays on (NOW, not before the problem). Any clue?? I am really trying to avoidthe dealership trip!!

For anyone interested......After checking EVERYTHING I could think of....I had it towed into a dealer to try reprogramming the remote to the car. After running diagnostics, turns out the power source control ECU took a dump. Part number for reference.... 89670-53010
