1997 Saturn SL1 will not start or even roll over. The battery is good but nothing happens when ignition turns. I got to playing with it, placed my foot on the brake and made sure the car was in park and after jiggling it for quite some time, the car engine turned over and cranked. I suspect that the BTSI solenoid is bad. I removed the center console and the BTSI. The long rod end seems to slide in and out with no resistance. I have had trouble finding another BTSI solenoid. Any ideas?

The neutral safety switch is located in the shifter housing.

Here is a link to a good article on this topic, that would beat an explanation from me.

Yes, it sounds like the NSS is the culprit.

Sounds like the safety switch that keeps you from starting the car when it's not in park is loose or is not making good electrical contact.

Get new key cut at dealer then insert into ign, Use object to tap strait in several times then jiggle key and rock steering wheel at same time.if this does not work will rquire new cylinder and housing.
