Thanks for the clarification.

We should start with some terminology discussions. You said initially that there is no spark, but I presume that you meant that it won't turn over. When a comment is made about no spark, it is generally understood that the engine is turning over but there is no spark at the plug to light the fire.

That said, your screwdriver test has established that your starter is fine. Note that there are four wires connected to the solenoid; two large red wires (that you crossed with a screwdriver) and two smalle wires of whatever colour. If you disconnect the small wires from your harness and then connect battery power to them, the starter should turn. If it does not, then the solenoid is bad.

Yes, the starter will spin if you cross the large red wire terminals with a screwdriver (assuming the starter is in good shape), even if the key is off.
