Recently inherited a fairly low mileage GL after my 97 outback bit the dust. It's got it's quirks (Hitachi Carb...) all of which are tolerable. Except for an intermittent problem turning over. Sometime it turns over immediately, other times it can be half a day before it decides to turn over. Just get a loud click, then nothing. Batterie's fine, starter seems to function fine when it does turn over. Should I be looking at the ignition, safety swith in the auto tranny wiring? Need a place to start.

 

Have starter tested.

Weak ignition switch.

 

Adding a pushbutton or relay at least ussually fixes it.

 

Sometimes replaceing the contacts for the solenoid in the starter is required.  Less than 20 bucks and takes about 45 mins tops.
