Weird no-start

Hello all,

I have a weird one. I washed the Jeep yesterday, when I was done it started to rain so I pulled it in the garage in a somewhat spirited manner. It was cold, and I perhaps shut it down quickly... Not sure.

Anyway, my wife went to leave for work this morning and the dang thing wouldn't start. Battery fine, it cranks over, but sounded like an engine with no spark plugs - you know how a motor sounds when it cranks - it has a cadence to it. This morning it sounded more like a "whir". She came to me for help and I tried. I checked under the hood for obvious issues, found nothing. Thought about how I had washed it... Nothing unusual. Got back in and treated it like an old carbureted motor. Gave it a little gas and heard some life. Pedal to the floor and it cranked like an old flooded engine and sputtered to life after five seconds or so of cranking.

Seems to run fine now. I thought flooding was a thing of the past, but I guess I was wrong. Anyone have any thoughts about what happened here?

Sounds like a few electrons got their panties in a bunch.

By holding the accelerator to the floor and cranking you initiated the "clear out" function. It's exactly as you described, the means to "clear out" a flooded engine. How the engine flooded is a mystery, but it worked. Techs will use it to start a new engine to get oil pressure before a real start. I use it on mine if there's a chance for the notorious dry start issue.
