Crank but no start no fuel no spark

? This true? Like a burnt out bulb. Never heard that before. If it is check the bulb to make sure its not burnt out.
I know if the ECU is not powered up the light wont be on. KOEO

 

Did anyone figure this problem out??

 

I am curious as to if you figured this out I have a 04 Tacoma with a 3.4 that last night had no spark. After reading this thread I noticed that the CEL was not illuminating with the KOEO, I called a tow truck and when the driver showed up I turned on the ignition to cut the steering wheel and the CEL was lit up of course she fired right up. I have never heard of a non working CEL being Indicative of a power issue with the ECU, but there is a lot I don't know. Planning on digging into the diagnostic today when I get home from work later and I'm hoping one of you fine gentlemen could point me in the right direction.
