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)?

Well damn.............Did a better check today. Tested dizzy, all within specs. So that rules the distributor out, all of a sudden Im getting spark from the wires, which was nice to see, but still no start. Checked the good book and assuming that I have no short/open in the harness (fun!) everything is pointing to ECM. My new question is this: Is it possible to still obtain spark if the ECM is d-e-d...dead? Im supposed to get between .5 to 1.0 VDC on the IGT terminal of the ECM, but im getting .006-.010....
To me it dosent make much sense, got spark, fuel, air good to go......is it a possibility that Im not getting "enough" spark?

The ECM almost never fries in our cars. If you are really curious, you can open it up and look for any burnt resistors, but I really doubt that you will find them.

You should check to see if your timing belt didn't break. An easy way to do this is to remove the dist cap, and see if the rotor turns as you crank the motor. Its happened to a few people on here before.
