New GP's and relay, still white smoke

Yah, I know. I have been watching new guys on diesel forums for years. Most of the time it's glowplugs, valve cover plugs or the relay.

well, last week, i changed my GP's and relay, inspected everything and changed the relay.

I waited over night so i could start the truck cold (7 C) or so and still a long turnover and lots of white smoke. It's not until the truck is at operating temp that the smoke totally cleans up.

Should have I tested continuity (sp) for all the pins on the valve cover gascut? I don't even know where to start???? I have tested the relay.
Is there a chance I screwed something up doing the GP's?

Thanks for any help

Scott

How old are your batteries? Same with the starter. Both have a huge effect on cold starting. The starters tend to "degrade" over time and you probably won't notice it (because it's still spinning, but slower). I was having similar issues, and after the starter totally quit I replaced it and what a difference. Also, injector poppet clearances will make a difference too (if you've got a buch of miles on them). Cheers!

Well, the battereis are new this summer. My last 7.3 had a new starter in it from last year and this truck does not sound to start any slower than my past one.

Injector poppet clearance, I am not sure what this is.

thanks for the suggestions Patrick

Cable condition? How much power is actually available at the starter.

How's the fuel filter look? Can make a big difference.
