the 93 legacy i am working on won't start it will spin over fine but no spark no fuel. i have power to the pump for a few seconds and power to the igniter and coils  but no fuel and no spark. no check engine lights at all so no power to the ecm. chiltons doesn't help much as far as power and ground to the ecm. a checked the fuse all of them all ok working on getting the relays out but they are up there a ways. why can't they make them more accesable? got the ecm out and it smells like ozone. is that normal? can these ecm's be tested or do i just sustatute?

It's very rare to see a failure. If you are getting the fuel pump prime then the ECU is being powered. I would be looking at crank and cam sensor signals.

Check for STORED codes>>>>HERE.

Check timing belt

They can fail but it's very rare. So rare that most people guessing, guess wrong and end up with a broken car and two ECMs.

 

No power to the ECM sounds wiring related.

I've seen a couple of cars that exhibited signs of ECM failure. Unplugged the connectors, untwisted/freed up any connectors that were in a bind. Made sure all wires were seated fully in the connectors and plugged back in, making sure all wires were free at rest with no side pull, etc. That fixed them. This should be one of the last things you do, the tips already mentioned above are much more likely to be the problem.

thanks i will try that . now where is the crank and cam sensor? i will pop the timing cover off tomarrow. i would do it today but i just got back from the hospital from a mild heart attack. so my wife says i have to rest for a bit.               

Cam sensor is on drivers side cam, crank sensor is just above crank sprocket by crack pulley. Look it up online so you know what it looks like. Attached with one 10mm bolt.
