Can only suggest the start relay K22 in the battery junction box or the starter motor itself.
Starter motors have a pre-engagement solenoid that inhibits power to the starter motor until it has engaged with the flywheel.
(older starter motors used to spin and throw out the engagement gear). So no, apart from maybe a click you might not notice anything.
The relay K22 is the relay between the ignition start switch and the starter solenoid, less likely but possible.
