help,turn key to start,no sound

[tigersvx]

my 92 svx happened from time to time,about 20-30% of time,
when i turn the key to start,all the lights show,but when turn key
further to start,no sound at all.

Before,i have to try again,and it usually starts after the 2-3 times.

Today,i went up to the snow parking lot,0 degrees cel.,and take me 6-7 times to start.

Is this the starter problem?or something else?

Is someone has a spare for sale?Thanks.
