Ignition Issue

[67ChevNut]

Rustypile, thank you.

I found a break on the purple wire near the starter. Also, another one at the constant hot red wire going to the ignition switch.
I had installed one of those quick disconnect connectors by the starter, but the connection was too weak and came loose. Same thing happened by the ignition switch when I replaced it.
Engine turns over with the key on now! It doesn't start though, it appears that I do have a fuel pump problem. I'll be checking the fuel realy and the fuel pump today. Truck is been parked for about a year now, I guess in-tank fuel pumps go bad when not used. Any advice on checking for issues with the fuel pump?
