Re: Hard shut off on 4.1l engine

I know there is atleast ONE wire going into the front on what looks like a selonoid. I'll snap a pic tomorrow.

Re: Hard shut off on 4.1l engine

Okay finally got some pics. The first is from the side of the carb, where the wire going in is where i suspect the selonoid is that adjust the air/fuel mixture. Am i correct?
The second is of the only thing i can find that can possibly be the o2 sensor, although it looks nothing like one to me.

Re: Hard shut off on 4.1l engine

I don' see any wiring to the top of the carburator at the bowl. So I don't think it will be a feedback carburator and will not have an O2 sensor.

What is the wire going into the side? Electric choke?

If your still having problem I think its your idle shut down switch its the part on carb on passenger side with a 9/16 nut with a allen screw in center with a electrical wire hooked to it. Its job is to shut off fuel and kill motor its also where you adjust idle . Mine went and truck just runs when you shut off key I had to get new one.
