Zirconxi thanks for doing all these tests, what you mention sounds all exactly correct and thanks for the feedback.
To your question; if hiss is not happy the fuelpump etc will not pressurize at startup as usual, so all is fine with hiss.
To confirm hiss function; make a shield for the key from alumunium foil big enough to cover the hiss coil which is the plastic piece around the ignition key with "start"etc. written on it and stick the key through it and try to start, all the lights and the meters work but the fuelpump does not prime the engine, it is controlled directly by the ecm ( pin e-21 see diagram above );
After so many starts it appears the battery is still holding up, i would charge the battery up before going any further.
This will do two things; it restores the battery capacity to do further tests and;
It will give the ecm a possibility to go back to a "refreshed state" whilst the battery is disconnected and set it's bits in memory to day one ( my assumption).
I find it hard to believe anything is broken and the ecu seems to be functioning as before, no fault codes are set so it appears all parts are passing the startup tests but it cannot decide where the crank is based on the lack of spark and thanks for testing that again.
Hope you have a good holiday and we are all here if you need some more help
