Is shaking on the right side what might be the problem?

Fuel guage showing empty. But car got petrol

Cant get front strutt out cant reach 3rd bolt under firewall

Car is locked and battery is disconnected so we can't unlock the doors to get the bonnet opened

Third plug is not firing I tried to change the plug and coil pack but nothing to avail
And also the rev count is very high and having misfiring sound
