Headlights killing the Engine
I'm posting this for the guy that bought my 7.3. The truck is a 2001 w/ 173k miles. He sent me a text this morning asking me if I knew what was wrong (I know that I'm under no obligation to help, but that's not how I am), here's the synopsis...
He parked the truck on a declined driveway (front of truck is pointing down) when he had less than a 1/4 tank. The truck stayed parked there for a few hours. When it was time to leave, the truck thought it was almost out of gas and died on him. After letting it sit on level ground, the truck re-established the correct fuel levels and drove perfect.
Since then (about a week ago) the truck has been doing something really weird. Whenever he turns the headlights OFF, the truck turns off. The truck starts and runs fine, just does this thing every now and then. Not all the time.
I'm not sure what the problem could be, and it's kinda hard to use the search function to diagnosis this problem - but I tried anyway. What I got was:
Maybe a loose ground somewhere, a weak injector switch, possible bad alternator, disconnect both batteries and run the juice out - then hook everything back up (see if that kills the bug in the system), and other things I don't believe to be the problem (fuel tank related).
What do you guys think?
