car died! no power to ECU!

[drifter808]

I searched but couldn't find anyone with similar problems, or maybe i just suck at searching.
so heres what happened, i was driving to go meet my girlfriend, and out of no where my car just dies completely. try starting it and nothing. no noise from fuel pump or anything. the car is cranking over just fine but doesn't want to fire up. So i had to get it towed home(what a rip off). Now today that i have time to tear it apart i was first checking the fuses and all of them looked ok and weren't blown. Then i check to see if the ECU is throwing any codes. Theres no lights or anything coming from the ECU. I've checked for codes before so i know how to do it. But nothing was coming on. I've had the same problems with an older ECu where everything looked fine inside and out but it was fried. Im gonna go test the ECU with a friends today, but im mainly wondering if anyone else has experienced this same thing and knew what the problem was. Or anything else i can test?

Thanks,Derek
