Went home at lunch and put the charger on the battery. The truck started up immediately with the charger hooked to it, but I left the charger on the battery during lunch. Within an hour, the charger brought the battery back up to 100%.
Thinking about this, I remembered that I had that ECM relay replaced just 3 weeks ago. Could that dang thing cause the car to have no power at all? No interier lights, etc?
