I own a 1987 nissan d21 truck, base, manual. It will not start. Has new battery.

What is your question?

I replaced the ignition switch and the starter relay. I try to turn it over and it just clicks once from the ignition area in the cab. I also checked the clutch safety switch and it's good. I took the starter/selinoid off and had it tested, it's good. I can start the vehicle if I touch a wire straight from the selinoid to the battery, but that's a pain. Any help would be appreciated. Thank you.
