For updates or revisions, please PM me, nuclerlemon or semlin The below is a troubleshooting guide if your in the boonies to help isolate a non starting vehicle problem. This is a compilation from forum members, specifically RavenTai, KliersLC, Landtank and Beaowulf. This will not catch each...forum.ih8mud.com
Check a few obvious things. Dist wire. Batt cables.
And it does have gas in the tank? Start with the basics -fuel, spark, and you have cranking confirmed.
BTW, since it's not in your sig line, what year truck do you have? That makes a difference in some cases.
Considering it died while driving may suggest EFI relay, perhaps? With key in On position in ignition is CEL light on? Follow Jon Held's No CEL/Start troubleshooting guide if that is the case.
Had this happen when I first got my rig: Check the 15 amp fuse (EFI) and the EFI relay. Mine popped the 15 amp fuse while driving; sounds similar to your situation. I highly recommend the alternative EFI relay from the Camry ala @jonheld. His information and knowledge of the early 80 Series is unrivaled in this forum.
Here is a cursory check of all 3 fusible links in system:
Dome lights working?
Brake lights working?
When you turn the key to ON does the CHARGE LAMP light up?
If yes to all 3, then all 3 fusible links are intact.
