I went through a little hole on a pipeline behind my house that I've been thru before but this time the ruts were good bit deeper and I was just sitting on the frame. The failsafe crap started flashing but the truck never died and I left it running til I got it out bout an hour later. The failsafe mode never showed up again but had a CEL on after that. Water wasn't over the tires but just over the bottom of the door sill on the driver side. After we got it pulled out it ran fine. Drove in to town to spray it off at the car wash and came home. (Left it running the whole time. Including some interstate driving. Ran fine. In fact it ran perfectly. When I got home I shut it off and back on just to make sure it would start and It did. Then went to bed. Next morning. One click and nothing. I have stuck a screwdriver down by the solenoid to jump the two cables and when I did it did click fast in a series. That's about all I know. Just really need my truck running hope this is something minor.
