Default no power inside car, can it be a ecu issue?

This morning when I was gonna turn on my car I had my key on ACC and all the gauges and stereo was working right but as soon as I turn my key to start the engine all the power went out. my battery is brand new I already test it and it has power but inside the car nothing turns on no lights, no stereo.. nothing!! I already checked all the fuses outside/inside and they are all good. can a burn or messed up ecu be the issue?

So your gauges, stereo and climate controls do not work but your car turns over fine and all the exterior lights turn on?

found the problem after spending all valentines day working on it. it was the relays on the power cable. replaced them with the ones from my Altima and everything back to normal I'm gonna have to order them from Nissan. thanks a lot guys!! now I'm gonna go get the drag slicks mounted on the new 15 wheels and see the results since its my first time on drag tires.

nothing was working at all!!! no lights, no cluster, no power at all inside car, for a sec I thought it was the ECU since I had the split sec piggy back but I took it off about 5 months ago and got tuned with uprev. but thanks god I found the problem I was about to take it to Nisan.

Got the same problem. The worst was that I am a handicap and the car died in the middle of the road and on traffic. I chk the battery and read 12.8v (2 mo. old). You say it is a RELAY on the power cable?
