Would cold temperatures affect a neutral safety switch? (Manual transmission)

Question

Trying to troubleshoot my 92 Subaru Legacy manual transmission starting issues.

Car wont crank/start most mornings, even if its only about 50 degrees F.

Replaced battery, starter, and alternator last year.

If the cars been in the sun for an hour it starts up either after a few key turns/pumps on the clutch, or right away.

Would a failing neutral safety switch be affected by cool weather?

James · Answer

It's possible.

Typically, if the NSS failed, the motor would not turn over.  Is that the situation here?

If you are able to start the car in gear with the clutch pedal depressed?  There's also a clutch safety switch.
