Check engine light for 89 SPG

I failed my local CA emissions check with my 89' 900 SPG. It passed the actual emissions test no problem. They failed it, as the check engine light does not flash on with the key in the on position with the engine off as it does in most cars. I suspect this is an actual problem. It should come on. However other 89 900 owners tell me that theirs does not flash on during cranking or with the key on. I
Checked the bulb it seems fine. I have been told it is most likely an ECU problem. Also that the 89' ECU is known to be faulty.
So therefore my questions are
1. Should this light come on during cranking in this year turbo SAAB.
2. What is a way to make it come on(disconnect the TPS etc)
I tried to ground the number 2 terminal on to pull codes and got nothing.
Seems like the ECU is bad?
Any one know where I can get a cheap good ECU from a 90-91 turbo Saab?
