K10 Not Starting

[rwrusso]

Hey all, I'm trying to get a 1969 K10 running so I can sell it. The truck was running recently, needed a jump in a Home Depot parking lot, it drove home, and now won't start. Won't take a jump. Apologies if this is not the right place to post this, but instead of searching the internet for answers, I figured this may be a better place to start. So...any ideas/suggestions where to start? I'm not a car guy, but fairly mechanically inclined, so hopefully I can get this issue sorted out and fixed in my driveway. Thanks.
