Fuel Pressure Regulator Question?

[dukey_78]

What are the symtoms of a bad fuel pressure regulater. when i put my edge evo on the high setting it has less power than stock but smokes, it is not the programmer tried another new one same then tried a superchip programmer and the same. The other day i was warming up my truck rite as it started to idle up it died went out to it and it fired rite back up. i really hope someone can help me out?

i would have a manual fuel pressure test run ,should be around 5o -60lbs , with key on , if you have evo programmer you can pull codes with it ,see what codes are there , is the oil in good shape and full

Like the oil in my truck if so i just changed it friday.

This moring i went to start my truck here in ottumwa iowa where i go to skool and don't have a place to plug it in at i ran the batterys down and had to get pulled over to the shop where i charged the batterys and plugged in the block heater i finally got it goin it ran really bad like it wasnt getting enough fuel once it warmed up it ran good. when i got around to pulling the codes i got P1209 Injector Control sys. peak fault, P0470 Exhaust back pressure sensor circuit malfuntion, P1211 Injector control pressure Above or Below desired. also a low voltage one too but i got that one fixed.

p1209 and p1211 are both oil pressure codes ,both could be caused by stuck ipr regulator on high press. oil pump, may have to replace it make sure hpop reservoir is staying full if its starving for oil wont allow enough to get to hpop which can cause your concern

if you have acces to a scaner that wil monitor data i can give you some more advise on maybe pinpointing problem a little better

[dukey_78]

I can get a genysis tomarrow morning and use or a solious

connect to truck ,monitor these values ,icp pressure not voltage , ipr % and
,ipr percent should be at 14 % with key on or just at idle , icp has to be at least 450 lbs to start , and shuld increase as you give it more fuel can go up to 3000 bs, ipr percent wil also increase but if way out or very erratic readings show up especialy high when cranking like above 50 % when c ranking , may make me think you do have a fuel pressure issue
