My 1990 won't crank, it is not a vats or key problem.

When i take out the starter relay, there is no power going to it, Can i take 12 volts and hook it up without damaging anything , ( the 12v would be going to the female end of connections,

The car will fire if i jump the solenoid , and hot wire the purple wire at the distributer.

Why isnt the car sending power to this rely?
thanks
