it...I joined the forum and eventually will subscribe to the scannerdanner youtube premium channel so i can learn more about vehicle troubleshooting. Right now i own a 1996 Mitsubishi montero that cranks but no start....has no spark, check engine light does not lid on the dashboard....there is no 5 reference volts at the sensors....and i cannot find the location of the engine power relay, so i can test it. I hope that i will find the solution within this forum and the youtube tutorials....

I will move your question into the repair questions section where it will get more response.
If I was working on your car I would do 2 simple tests to find out if your engine wsn't starting because of lack of fuel or lack of spart or lack of both fuel & spark.

If no 5V then check powers and grounds for the ECM.
You need to verify your ECU FUSE is good. Mitsubishi tends to throw out a bunch of stuff on one power feed. So if it’s a blown fuse don’t touch anything before doing a visual inspection. Do you have a test light?

Age has effected the electronics inside it and there is no way around it. Rather you buying a used one and trying to get it to work with your vehicle only is putting you into the same situation. For your experience though trace the wires and stuff. Mine had no spark via no signal from the ecu. Try these people though because it seems they do your year... not sure who I used. www.fs1inc.com/engine-control-modules.ht...=Rebuild%20(Rebuilt)
How do you come to the conclusion that in this case the computer needs to be rebuilt?

Maybe he is drawing unlimited conclusions from limited experience. ........

If you have power and ground at the ECM, start unplugging engine sensors until the 5v ref comes back up then you will have found your problem. Thermistors aren't going to be the issue due to them having a different design as outlined in Paul's book.
If you don't have good power or ground at the ECM, then you have a heck of a good direction to follow!
