I am a new owner of a 83 GMC with a rebuilt 6.2L about 45K on rebuild (runs great).

When I start my truck at about 40 - 30 degrees (coldest it's been this year) it smokes from the passenger side once it starts - white unburned fuel. When / once warm no smoke at all. Truck never smoke otherwise.

I figured bad glow plugs. I checked all eight and they are good. I removed the wire and did continuity check.

Is it possible I do not have power to some of the plugs? Is this a symptom of a bad controller? What is the best way to troubleshoot this issue?

Is there a way to tell which type glow plugs I have without removal from the motor????

I love my truck and I want to take good care of it. Thank you for your help!

Check to see if the plugs are getting power and go from there. I would guess your problem is in the wires.
