car won't stay running 65 Buick Riviera

[coast 13]

When I turn my car over it fires and will run as long as the key is engaged. Once the key is let off it dies.

 

I noticed my ground strap is broke? Could this cause this issue?

 

What other places should I check.

Thanks

Does it die when the key returns to "run" position from "start"? If so, it may be the ignition switch.

yes

Sounds like a bad switch (as mentioned earlier) or an open connection on the resistance wire from the switch to the firewall connector.

 

With the key in the RUN position, check the coil to see if you have voltage.

Step 1, this sounds like voltage is dying at the coil. Get volt meter, turn ign on and check voltage at coil(should be 12v or close to it). If not, check your coil wire under dash. Probably cooked.  PM me, will guide you through repair. FYI, it's probably your switch that caused it. More to it.

also sounds to me like the ignition switch is disfunctioning
