CEL codes

I recently installed the "blue" spring on my fuel regulator to correct (what I thought was the problem) some CEL codes that I have been getting.
The codes normally show after getting hard on the throttle, and does not come on normal throttle. The codes indicate "low fuel pressure on Cylinder 1,3,4,5,7,8 (sometimes on all cylinders), and fuel level circuit A low .
The filters are recent, the HPOP was replaced about a year ago (due to sputtering under power), and the EGR delete was installed. Now I can't figure out how to correct the low pressure to cylinders.
