Hi highliner1, Welcome to 2carpros and TY for the donation
Our truck will not re-start when warm, unless it sits and cools for 30 minutes or so. Don't wait for nothing do below immediately
Pick your symptom below and perform the checks and get back with me asap with some testing results
Cranks but no start condition:
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems
with compression and valves opening and closing at the wrong time/broken or jumped timing
belt/chain.
No crank at all/nothing/nada:
Could be the starter, starter relay, park and neutral switch/clutch switch and ignition switch assuming the battery and connections are good
