Hard starting...i know, i know....
hey guys...
first off...i know about these threads but couldnt find what i needed from searching...thanks for understanding
ok my truck is very hard to start in the am and after work...sometimes even when stopping at the store, etc.
a little info...have fresh oil 10w40 T5, oil full, hpop full, new fuel filters, new black cps from clay, newer batteries(checked voltage 14+), new alternator in summer, cleaned and checked all connections today, new stancor GPR, ohmed GP(all about 3 ohms), new tstat and no boost leaks. im probably missing something
anyway...it is hard starting and there is a good bit of white smoke when it starts. it even seems to have white smoke while idleing in the driveway...my daughter like heat on her way to school. it doesnt smoke while driving though. i have tried about everything i have read...so can someone plz help out? thanks alot in advance, this starting thing is driving me crazy

If nothing else, consider this a bump 
Ok, so white smoke at startup could be bad glow plugs or bad GPR, or the truck is simply too cold to combust the fuel. White smoke in the exhaust while running indicates unburnt fuel that has not combusted in the exhaust. Causes - broke lifters, bent pushrods, bent valves, stuck injector etc...
So, if you only have it at start then something isn't right with the GP or GPR or just too cold. But you've got that checked, and the GP LED mod says they're working (right?), so..... it shouldn't be too cold for your oil. Have you tried plugging it in? Does that affect the start?
How are the injectors? If one is putting out too much fuel, like a broke tip or stuck, it should have other problems, too. Does it eventually run ok?
Does it romp or clear up once the engine is warm? At the store- hot or cold engine. You've deleted the EBPV, how did that initially affect starting? Is this the first winter since you did that?
You have a lot of mods, anything done recently?
Ok, probably not much help, but bump nonetheless.

Isn't 3 ohms to high? I thought that glow plugs should be 1.5-2 ohms max? just might want to check that. go to your local parts store with your meter and check a new one.

When it gets below 40 I leave the key on for about 40 seconds then recycle key and wait about 5 seconds to allow FP to built up pressure and then it starts right up.
Edit : This method also works down to 20 degrees

I was? I'll be honest, Chris, I work on so many trucks I forget what I find on what. Just throwing out ideas.
