2002 7.3 wont start cold

hey guys im new to the forum i have a 2002 f550 that has 255,000 it is not wanting to start after letting it sit over night.It seems to start ok in warm weather after sitting for one day but if you let it sit for two days it wont start.now its cold here and it dosn't want to start after one night of sitting,also when it wont start but finally does the throttle wont come up for about 60 to120 seconds with foot to the floor.this is what has been done so far-its been in two shops and it has 8 new injectors and new gpr's,new icp and fuel drain hsg,new alternater,starter checked,compression checked,gp's checked,batterys checked and swaped with other truck,hpop is 3/4 of an inch from top,someone suggested ipr the other day but i'm not sure any suggestions would help.thanks

I dont really want to plug it in because for the last year and a half i always had it plugged in day and night due to some bad inj's but i did plug it in twice since back from shop because it wouldn't start at all,the funny thing is,i have put a jump from my other diesel before and it did start,but the last time i tryed that it wouldn't so i kinda ruled out the volts but dont know.
