94 camry possible bad ECU

[waveslayer]

Driving down the road the other day and the car died. It hasn't fired since. No fuel, no spark and all the fuses and relays are good. No power to the fuel pump, and no spark... Could this be anything but the ECU?

Um, Alternator died? No power?

Nope can't be alternator, battery has plenty of juice and the motor doesn't have to be turning over for the fuel pump to spin up after reseting it by disconnecting and reconnecting the battery. The key just has to be to the on possition to send power to the fuel pump, and their is no power at the pump or beyond the open circuit relay. When the engine is turned over their is no spark. The only thing that links these two problems is the ECU. I'm just wondering if theirs anything i'm missing..
The alternator doesn't play a roll in the fuel pump circuit at this piont i don't think... I believe its just the EFI relay, fuse and Open Circiut relay. Their also is no current being sent to the open circuit relay from the CPU..

When you turn the key to the on position, does the Check Engine Light come on with the rest of the dash lights for the POST check?

The ignition switch could possibly affect both. It makes several different connections when turned, not just one.

I recall that the ECM will shut down the fuel pump if it gets a mal-function signal or no signal from somewhere. I think it is through the distributor pick-up coils but I am not certain.

Toyota ECMs are very reliable. It is usually something else, though not always...

Timing belt broke?

Battery posts loose or corroded? A similar thing happened to me a few months ago when the posts were loose.
