P1104, P1105 Boost/Vaccum leak?

[805LegendDSM]

Duplicate alerted yet I'm sorry but still had to ask in my own words,

Have my GSt for about 2 weeks now, did 2 weeks of searching reading thread after thread from this forum to others, and still ant get solid answers, I even posted about this topic on here 2 weeks ago and got no answer to a simple yea or no question.

So here's another one.

My car has 2 codes, P1104 & P1105
Fuel pressure solenoid
Waste gate acuator

My FPS is not hooked up to the manifold or regulator, since I have my FPR hooked up directly to the the manifold (which I heard it was ok)...

Does the Fuel pressure solenoid have any other job but just stay open or close? Like does adjust fuel ratio readings dumping more fuel?...

Can any other bad solenoid or sensor cause the Code P1105 to go off? Besides the solenoid itself?

The p1104 is no stranger to me, but in this case can a vacuum leak or boost leak cause this code to go off as well? Yes or no?

These all can be yes or no questions guys. I don't expect everyone to tell me exactly what's wrong or how to fix or go into detail...because from looking around I see a lot of plp just going off telling other guys how lazy they are and how they have to search and such.

Do you have a vacuum delete? Did you just undo the vac lines and leave the solenoids plugged in? If not, that's your problem. On a 2g the solenoids have to remain plugged in or they throw the CEL.

Yes, my Fuel pressure Solenoid is plugged in. It's not dirty either plug looks fine as well as the sensor.

The car is completely stock...nothing missing/deleted besides the stupid bypass of the fuel pressure regulars which I done yesterday ...

Stock Boost controller is plugged in as well if that has any relation to the p1104
