Timing Off aprox 90Deg? (was ECU/ECM Problems), So it finally died (renamed topic) Options

[Spider77]

A few days ago was driving the celica and out of nowhere it just died. Luckily enough I was able to get it towed to my house for free (well, insurance). Thing is she wont start. I know Im getting fuel, and compression checks ok. I'm not getting spark though, I've got it narrowed down to either the dizzy or the igntitor, some resistance readings tomorrow will clear that up. But in the meantime, I was wondering if anyone had problems with their ignitor before, and if you have, is the just a way to check the actual item, as opposed to ruling everything else out (by checking ECU, Ignition Coil, and connectors/harness)?

Engine Cranks But Fails To Start
* Ensure proper spark exists from ignition system.
* Ensure ignition timing is correct.
* Ensure fuel system performs properly (fuel pump, fuel filter,
fuel injector, fuel pressure regulator).
* Check Electronic Control Module (ECM) and wiring.
* Check airflow meter or vacuum sensor and wiring.
* Check idle air control valve (if equipped) and wiring.
* Check circuit opening relay and EFI main relay.
* Check engine compression, valve clearance, valve timing and
timing belt (if equipped).
Right outta book...........Verified spark, Timing good, cylinders get fuel (car reeks of gasoline after too much cranking.), ECM fails check, so thats where I am so far.
Too add, I know the belt is good cause I puled back the cover a bit and had my wife try to start the car, belt checks good. Im not saying the ECU is fried, but "having" issues....I get voltage, but real minimal voltage, not even enough to meet the minimum specs...
This is for "Tests W/Out Codes", cause I pull no codes.

Check the circuit opening relay and all of your fuses. The relay is located right next to your ecu.

Just curious how do you know you are getting fuel? That is a classic symptom of an electric motor going out. Sticks a few times , cools , wiorks, finally goes out. Also I had a bad coolant temp sensor(it was corroded inside and cracked but looked fine from outside) and my car had the same type of symptoms.
Good luck
