Does the car have a immobiliser ?, get someone to turn the key and hold it in start position whilst you whack the starter.
If you apply 12v from the large 13mm nut from the battery side of the solenoid to the terminal onto which the feed wire from ignition switch goes it should spin over nicely, if it doesn't either lack of power or dud starter.
Take a voltage reading at starter 13mm nut when in start pos, if it drops substantially with no sign of life then dud connection/battery, also test the ignition switch feed to the terminal for voltage, if this drops markedly then may need the terminal soldering on end of wire, these bugger up connection wise, done a few of these.
