Heavy white smoke cold start

[Pstyckiewicz]

So I did test the voltage to the wires last year when I changed the glow plugs and they got 24 volts. Also the voltage drops on the gauge during the wait period. But I’m not knowledgeable in the glow processes. I still have to test the other 4 glow plugs on the passenger side.
My exhaust on a cold start is defently a massive amount as well. Like fill my yard and make my clothes smell like unburnt fuel after I escape the fog haha.
I’m leaning towards the glow system as well. I will recheck the wire voltage and check the other glow plugs.
Just trying to narrow it down before I start throwing money at it.

I've read here before one bad plug creates a kot of smoke just because of the unburbed diesel, two or more are exponentially worse.

I recently started to get some white smoke on startup, and I suspect that one plug i didn't replace last summer because it ohmed good and i ran out of time. I'll re ohm and probably replace it this weekend. If it changes anything, I'll report it here.

Started truck and took the 569B wire of the injection pump and then reconnected it. I could hear the difference when doing that.
I tested the driver side plugs today and they all registered between 1.2-2.5.
I also plugged the block heater in for an hour then started it……no smoke. So glow plugs?
Can 1 bad plug cause a bunch of smoke? I have to test the other side still.

You have a lot of good knowledge here on the site.
With that said, I had a issue sometime ago with rough start smoke for less than minute when starting.
It was a simple glow plug boot on just one of the cylinders not making good contact.

Tested a glow plug wire. Getting around 20-21 volts.
