flooded engine?

Left for work this am and it was cold maybe upper teens low 20's. I started up the truck and let it idle for a minute started out and stalled. When I tried to restart it wouldnt start. It took a couple tries but eventually got going again, I had to give it gas and what not. Question is this, did I actually flood the truck out? I didnt think it was possible to flood EFI, also would it be worth while to check to see if a plug got fouled? It ran fine on the way to work. I wonder if I did any damage to the starter? thanks

Could be tons of different things, but one that jumped straight to my mind was that your idle air control plunger got stuck.

Yes, it is. EFI does not (and can not) check if there was a spark or enough air in each cylinder, so fuel will still get into each cylinder.

If it happens again, and you suspect the engine is flooded, try unplugging the coil. This will help clear the cylinders. It will start then sputter out. Reconnect, and the engine should start, assuming there are no other issues.

I would suspect just the opposite. It isn't going to start without the coil connected and it floods because there is no spark in the first place.

Did you mean unplugging the injectors or computer?

He means to unplug the fuel injection signal connection from the coil. It will stop firing the injectors to help clear out the fuel.

Yes, that's what I meant. It's a little plug on the bottom, IIRC. Maybe I just need to stop dispensing advice.

Nah sorry. I just read coil and was confused. Sorry.

This may not be the case but when I had a 3.9 I had very similar symptoms before my cpu went south.

It was flooding horribly, thought it was the optical thingy in the mallory distributer, which was fried, but when I put a new one in it fried too. turned out to be the cpu...I'm not saying this is your problem just an FYI.
