Got down to the mid 30's this morning and now my truck won't start. The "Wait light" comes on then goes off like normal. I turn the key and it cranks but wont start. Tried numerous times.
HELP
Looks like it is the glow plug relay. With key off had power to one lug on relay. With key on had power to one additional small lug. The relay should have sent power to the second large lug when the key was turned on but it didn't. Bye the way. Now that it has warmed up outside it fired up like normal.
