I’ve found wiring diagrams on line @ autozone for free for my2006 Dodge Caravan. Crappy Hanes & chilling manuals are going for north of $25 if I remember correctly. 

Peace,

Mark, other than the usual traditional suspects I'd check Google and
YouTube. I'll bet you could find instructions for brain surgery on YouTube!

I've also found the Haynes on-line to be useful, sometimes. I have lifetime
Haynes subscriptions for our '02 Suburban and '07 Accord, but by the time
we bought our '98 F-150 they'd gone to annual only, which ticked me off
somewhat.

I'm guessing you have a code reader. Does it offer any information?

I don't think any of those came in manual, so I'm assuming it has an
automatic transmission. I'm also assuming that, aside from the starter not
cranking, everything else seems okay. Does the fuel pump prime? Does the
starter solenoid fire? Is the battery in good condition?

Assuming you hear nothing from the starter, I'd start with the starter
relay, and if that is fine, I'd look at the neutral safety switch. What
happens if you jiggle the transmission, or try to start in neutral?

My first step will be to check the battery connections and the starter 
wiring.  I wonder how long it will take me just to find the starter?  
And what I'll have to remove to get access?

But I am 'currently' charging up my portable power pack, will keep that 
handy in the vehicle.

As others have said, there's probably nothing too complicated for YouTube.

Battery (unlikely), Neutral Safety switch, Ignition switch, starter
solenoid.  In the olden days, GM electrical ignition switch modules were
mounted lower ont he steering column, making them relatively easy to
access, test, and replace.  Operated by a rod coming down from the
mechanical portion.

So, when it fails in Park, does it start in Neutral?
