Might sound stupid... Turn your turn signal on. I don't know why, but my car will not crank unless I have a blinker on...
Neutral safety isn't working, if you have a manual transmission you need to ground it, automatic, check your switch (transmission).

Theirs connector on the solenoid needs to be grounded for the solenoid to work, typically it hooks to your neutral safety switch.
Yup, but that is the way factory manual cars were of this era.Yep Im guessing that you should, but be careful she'll start in gear with that grounded.
Don't confuse the issue, he has the wrong relay installed.The fact that it cranks when you jump the solenoid connection to the battery lug on the relay tells me that there is a good ground at the solenoid coil. I would bet you either have and issue with the ignition switch, the ignition switch connector or the bulkhead connector on the firewall.
Sorry I didn't see that he installed the worng relay.Don't confuse the issue, he has the wrong relay installed.

Whereas that may be true these cars didn't originally have clutch switches.
