White smoke when cold
I've noticed the past few mornings that when I start my truck in the AM it will chug a fair bit of white smoke for a few seconds. I thought it was kind of strange since my GP's were replaced with Motorcrafts around July sometime but didn't worry too much about it. Yesterday I started it up and was moving the car seats from the Exploder to my rig and noticed that even after idling a few minutes (long enough to let the high idle kick in) that it was still puffing a small amount of white smoke from both tail pipes. Not very much, but noticeable when you look close.
My question is, what could the problem be? I still need to put the DMM on the GPR and see what its doing. I know it works at least somewhat because the dash lights dim down and stay that way for about 2min on a cold start. What are other potential problems I should be looking at?
Early turd 99, stock injectors (no injector work as far as I know), stock GPR, EPBV unplugged, new glow plugs last July, no tuner, 01 PMT2 PCM, 6637 intake.

Dude, it is on it's last legs, it is about to puke. Set it on fire and get an insurance claim.
Not really.
Mine smokes like nobody's biz when cold. It is seriously annoying to me. Been that way ever since the new injectors. The jectors give great power, but cold start smokies are annoying as he!!. I would be bent out of shape except I saw the same thing in Swamps employee trucks when they first started theirs last winter. What can I say?
If you find it out let me know.
I know, different situation but at least a bump to the top.

Other than making sure your air intake heater is working (most of us don't have one anymore), there's not much you can do except wait until it warms up enough to burn up that white smoke.

No AIH, mine's an early bird. If it's normal I'll stop worrying about it, but I didn't think these trucks were supposed to smoke that much when cold.

EBPV is unplugged because last time I tried to drive with it plugged in, it would flap shut on decel. The EBPS tube was checked sometime last summer, not plugged up and no holes.
FWIW, after changing oil/filter and fuel filter yesterday I cycled the key a 4-5 to fill the fuel bowl back up. Just doing that pulled my batts down so low the truck wouldn't crank. 30 minutes with the jumpers hooked up and finally putting a portable jump starter on the other batt got it to barely fire, so I went to WalMart and bought 2 new batts yesterday.

Since I put the swamps single shots in mine smokes like crazy when you first start it if its cold. But it runs great. But it still bugs me to see the white smoke.
I still have not got the program changed this could have some thing to do with it.

Yep, if it's in the low 30's or colder I get a some white smoke too. She starts up quick, might romp once, smokes a few seconds then clears up. I'm not gonna worry about it, she's old enough to smoke !

I keep forgetting to add- after letting the truck sit overnight I tested the GPR before turning the key on in the AM. With the key off I got 12.4v on one post of the GPR and nothing on the other side. Once the key was turned on, the voltage dropped to around 10.5v on both terminals. Should there be that much voltage drop when the glow plugs light off?
