I’m getting multiple misfires mostly cyl 6 and 8 now it’s saying 5 and 1 too I figured it was hpfp bank 2 so I threw that at it all the coils and plugs are new already lpfp is new maf sensors are okay, throwing a p0171 and an 11A102 (Fuel high pressure 2: Pressure too low) any ideas???

Make sure to check that your Coil packs and your Fuel Injectors are installed nice and snug, most common issue is that these are mistakenly installed incorrectly.

I’ll check that even though I haven’t touched it before all this have you seen something that before especially after I swapped coils and whole 9 yards I made sure they plugged in

Running any custom fuel maps/ Tunes?

No

How many miles on the car?

Did the cyl 1 and 5 start missfire after the coils install? May be defective coils?
