My vehicle is not starting. I have a new battery new starter and new terminal connections, but when I try to start it it clicks once then nothing. I am almost positive it is the neutral safety switch, but I cannot find it so I need to find where it is and hopefully find a way to bypass it until I get a replacement.
Do you
have the same problem?

What is clicking, or how loud is that click? Feel if it is coming from the starter relay on the inner fender, near the battery, while a helper turns the ignition switch to "crank". If that is what you are hearing, tighten the two soft copper nuts on the two larger studs.

To bypass the neutral safety switch, unplug the red/blue wire from the starter relay. Momentarily connect a jumper wire from that stud on the relay to the battery's positive post. Be sure the transmission is in "park" when you do that.

Not sure where yours has gone but this picture is what the neutral switch is supposed to look like.

That's what I thought, but Rock Auto shows a screwed-in switch at the rear of the transmission. I was confused because the switch can't just fall off.

I believe the screw in would be for a manual trans.

There optional trans didn't have a picture but here are the instructions that sound a lot like what you're describing Doc.
