Hello HT crew!

i have a serious issue of the thing that the car won't just start, no fuel pump will buzz and the starter just won't spin..

the issue started 2 weeks ago, i dorve to the other village and was there, then cruised one lap around the village and parked again. i did not put the alarm on, just i closed the doors.
was there just about 15 minutes and when i got back in the car, the OIL and BATTERY lights, what should be bright when to turn the ignition to ON. but they where like extremly dim!
i thought that whatta?? i have a 96Ah battery in the trunk and strange that it could not be empty!!
then me and my friends pushed the car like 3~4 meters and it went on like wrnnn!

then i let it just runn to charge the battery if it needed. but when i turned off, and back on, then the same issue.

so then i drove back to my place and charged the battery, now it is charged. but still the same.
i even checked for the interior bad ground, i fixed it too, because it looked like this:


and still no result.. tryed also to change the main relay, and still nothing.

when to turn on the ignition key, it makes no fuel pump relay buzzing sound and it also won't turn on the starter to spin.. so it is SUPER STRANGE!!

but everything else elctircal works, the alarm, windows, moonroof, radio, headlights..

i searched here and googeled, but still the main relay issue, but i think i don't have it, because when i turn back he key, then the relay clicks like it should be..

ohh, i am so confused, but can anyone please help!!!!! what could it be???
