FYI the clicking sound when starting is a result of low battery voltage.
I've seen this several times in autos. What happens is you turn on the
starter switch which causes the starter solenoid to engage. The starter
comes on line putting humongous load on battery. Battery can't cope and
voltage drops so far that starter solenoid disengages. Starter load is
gone and battery voltage recovers and starter solenoid reengages etc.
The result is a rapid clicking sound.
This can be the result of an old battery or corroded battery cables or
corroded battery terminals or discharged battery or alternator failing
to charge the battery or bad starter or intermittent connections etc.
Basically you just have to check everything.
