| The starter relay coil ground in a manual transmission car is provided through the clutch interlock switch. Try jumping it but do push in your clutch and be in neutral for safety when you try. The starter relay may not be getting power from the ignition switch. Does anything else turn on when you turn the key? If so then it may be the case that your ignition switch is bad. And then there's the theft warning relay. For the ground to make its way to the clutch interlock switch and then to ground it first has to go through the theft warning relay. So it could be that the theft warning relay or the theft warning control module that controls it is bad. So if you have voltage on one side of the starter relay coil when you turn the key to start then either the clutch interlock or theft warning relay or its control module is bad. This is of course if all wires to each are good. Do check continuity between all before replacing anything. If you have voltage on one side of the starter relay coil when you turn the key to start then I would try jumping the clutch interlock and if that didn't work try jumping the wires at the normally closed (according to the FSM) theft warning relay. One of those should do it unless you have been trying multiple bad starter relays. You can test those out of circuit pretty easily.
