Thanks God, it worked. Mr. G-Benz gave me a hope and it happened. Today I opened the engine hood so the sun rays can dry as much as possible for about two and a half hours (just imagine Kuwait's heat above 50 degrees). After that I gave a shot and discovered that it worked on 12 for about 2 seconds only. Then at night I gave another shot and thanks God, bingo, it worked on 12. Now I need to get it diagnose to see what codes are remaining (if any).
The only remaining problem is that the SRS sometimes lit the shutoff while the engine is running. I'll let you know about updates.
I really do thank you all guys about your support
