What just happened?!

It has been raining a lot

 

These trucks don't have distributors. They have individual coil packs connected at each spark plug.

 

There is no distributor. The 4.0 is coil on plug.

 

Mine has done that quite a few times. The times it has happened would be when I get back in the truck to start it and after I was sitting in it listeneing to music and drinking coffee before work. You know with the key on accessories. Another time is when I was hauling ass down i5 in a rain storm. Got home or where ever I was going and the next time I went to start it it would do the same thing. Freaked me out the first time it did it. Now I just raise an eyebrow at it. Maybe it had a fart in its brain. Idk

 

ok check the plugs?

 

My 4 cyl will get weird sometimes after crawling down long super steep slopes in 4L. By steep I don't mean paved streets, I'm talking about ~50% grades out in the mountains. It idles low and is sometimes hard to start for a little while (10mins?) after that. I've posted about it before and others reported the same thing. Never have figured it out, it doesn't affect anything really so I just ignore it. Possibly related?

 

Parked on level spot, 34 degrees with a half tank of gas - started right up

Note I did let the key at accessory for a few seconds listening to the sounds it makes

 

There you go.
