Thank you Airsley. That would be the 3 relays that all look the same?

No idea, but that would be a easy fix.

Having a intermittent issue. Only happens during warm weather and after a long haul. Never does it during winter. Shut truck down after a long haul. Then try to re-start and get no wait to start light and just cranks. Let it cool down and light comes back and it fires. Has me stumped. And no I...

Or maybe just air in the lines?

So....long story short. Wife has been driving my truck. Calls me at work and says truck died. I get there and its a no start, no code condition. Automatically I swap out the CPS. But then I check oil level before firing it up. Its 7 quarts low! Find out that my high pressure oil crossover has...

Ok, thank you ghohouston.

yes its chipped. ill yank it and see.

how does that tie into the lack of WTS light?

yes, i had just pulled a couple cords of wood out of the forest and drove home, turned it off to unload and went to start and got nothing. let it cool off for an hour and it fired.

:fustrate: well after waiting an hour it finally started. must be a intermittent issue with the pcm. crap.
