Everything was perfectly fine I drove out to the woods today parked the truck got the equipment runnin so I hoped back in and started it up while everything was runnin. Went to get in it to sit in the ac for a minute and nothin.radio won't come on glow plugs won't come on blower motor nothin.i can jump the starter cylinode and get it to crank but it won't start. I can cycle my glowplugs with my push button also so it's not battery related.any ideas on what it could be.im thinkin fuseable link but I'm not sure
Also the nss is bypassed

Fusible links are a prime suspect. Other possibility is main power from the battery + to the starter relay junction. SOME '83-'86 trucks are wired "backward" compared to later ones, whereby the main + power goes from the battery + to the GP relay and then splits over to the starter relay. In any event, check ALL that.

Does anything work that doesn't require the key? Headlights, 4-way emergency flashers, etc?
