69 Blazer- No Start

[Savage69K5]

Guys,

Fighting a no start condition on my 69 K5. It is a 350. Original problem was not being able to start the truck. Everything on this truck is ancient, so I haven't had a problem replacing the battery, alternator, and starter in an attempt to fix it. (Distributor is only a few months old)

Replacing the battery and alternator still did not get it to start (both were bad anyway). I wouldn't even hear the starter solenoid click. After changing the starter, I did get the K5 to start immediately, and multiple times (last night). However, this morning, I tried to start it again, and it turned over. However, trying again, all I get now is the solenoid clicking. It almost feels like it isn't getting juice. Is this now a wiring problem since I have eliminated several of the other variables? Battery cable maybe?
