I would think it would be black smoke then though. Im wondering if he has low compression on one or more cylinders. That would cause an incomplete burn and explain the hard starting....

does all that smoke clear up once the engine is up to operating temp?
what condition,where did you purchase,and what model # ip did you use? (rebuilt,pulled from another engine,etc)
what are the condition of the injectors? normally such a condition as this,is caused by faulty injectors.how many miles are on them? you didn't state replacing those at the same time as the ip (which is ideal.)

he said it smells like raw fuel as far as the low compression he said earlier that it didnt put out this much smoke before the ip swap and it would be a fluke if it just up and dropped a cylinder as soon as he did the swap.

where did you get the new ip?im thinking its an ip issue but i have been wrong a few times ,especially when i run on hardly nothing for sleep like i have for a few months now.lol

FORDF250HDXLT- No the smoke does not clear up at operating temps. The pump is a rebuilt Stanadyne DB2 pump form dieselcare.net and I don't know if the previous owner ever replaced the injectors but i didn't

Country boy- the timing has been advanced and retarded and there is no difference in the smoke

99% chance of bad injectors.
lets hope it's not a bad ip though.iv read a handful of poor results with their ip's.
id be quicker to suspect worn injectors just showing their age with a fresh pump.

Is there an easy way to check the injectores? Or would it just be easier to replace them?

well it could be something else,but since it started once you replaced the ip,it kinda points you in the direction of worn injectors (most likely) or a poorly rebuilt ip (not so likely despite some poor reviews.)
look at it this way,the truck appears to be a decent truck that's clearly got (at the very least, based on the pics in your garage) 5 more years in her (likely much,much more.)
so your out nothing at all by providing her with a complete idi tuneup right?
(ip and injectors should be replaced together every 100k ideally.)
if she still smokes like that with a set of fresh BB codes,then you know you'll need to return the ip for another one since it didn't do this before the swap.
but you didn't loose out in this case by using the "throw parts at it" type of diagnosing,because the odds are even if they are not causing the white smoke (i really doubt this) they are still due for changing as per recommended maintenance anyway.

all this is assuming (and we know what i get for this lol) that you correctly swapped the ip,and have the timing marks close to ball park range (lined up or a little toward the pass side) with a good healthy rattle.

What are BB codes? And I'm looking for a set of injectors now if you know of any good retailers or brands I'd love to know. thanks

BB code injectors.most swear by them.i like mine.probably would have liked a fresh set of E's just as well i dunno.
factory turbo engines got the G codes.
if you want to see what others say about all the codes just search.im done repeating info i don't know about personally.i can't tell you BB's blew my old E's out of the water or anything like that.they fixed my issues with shot injectors is all i can tell ya about 'em.didn't seem to do nothing less or more.
whatever you decide,you can get 'em all here:
7.3 L Ford Diesel Fuel Injectors Fuel Pumps Accessories

if you want a real performance injector you can get 'em here:
IDI Products

i know Dave S run those with great results with 20 lbs of boost setup.
probably not what your after without their pump,head studs etc.cus id think you'll just over fuel and get no where lol.
