Cummins ISX15 2013 won't start and cranks over and turns off right away

[Shokar92]

Anyone know any place I can get a reliable turbo with actuator??

My current turbo is

Assy: 3781362
Serial# P1301300124
Cust:3781369
Model:HE400VG

I was looking on Peterbilts online website and I cant find this one

I also looked at Quick serve and I still cant seem to find one

my engine serial number is 79637834

Another question I have is, I seen some turbos with Turbo and actuator put together.. that are rebuilt..
{name removed} has those listed right now with different part numbers but would those turbos require you to take off the actuator before installing it? and using insite or could you simply "plug and play" with those ones..
