Default Replacing the ECU

I have been having all kinds of troubles. First the car died on me the other night as you may have read. So I checked the engine codes and went through the steps in the manual. Everything seems to be fine. I checked the timing belt, it was okay. The car won't start like it isn't getting fuel or air or a spark. But when I checked the spark it seems fine. So everything is starting to point towards the computer. Now when I looked these are not cheap. Is there any way I can have the computer tested to make sure that is the problem before a drop this kind of money into a part that might not be what the problem is? Does anyone else have any ideas what it could be? I have checked the fuel (didn't have a presure gage but there is pressure) the intake is not blocked. I have checked all the vacume hoses and everything seems fine. The only other thing that I could think of was the main relay. I am too damn tired at this point after working on the thing for 5 hrs and working since 7AM. How do you remove the main relay. I found it but didn't have the energy to try to figure out how it came down. If anyone can help me any I would appreciate it. I am at a loss. I want my lude back!! So if you know if you can test the comp please let me know. Thank you in advance!!

Do you know if that ECU would work on mine? It's a 92 Si4WS It has the 2.3l and is 5spd. But I think I need an ECU from a 4WS lude. Also I don't know anyone else with a 4WS lude. If it is interchangable with the Si non4WS model I could try it on someone's car. I wish I knew more about the ECU. Does anyone know any good pages to read about it?
