fuel pressure regulator

Been having a bad miss in my 03 6.0 195,000 mi 4in turbo back exh, k&n air filter, egr delete. Reading codes on a handheld was useless, so I had ford run diagnostic. 3 bad injectors, the tech advised to clean fuel pressure regulator, where is the reg located, I saw a pic of one on ebay but I can't find it on engine.

I don't have any pics in my photobucket, but search out "blue spring mod". The updated spring is the fuel psi regulator.

That's what the Ford tech advised? If he ran diagnostics and found 3 "bad" injectors then how is cleaning the 'fuel pressure regulator' going to fix them. Find out what the codes are and then post them and the tech's on here can advise a better route to take. Good luck.

I agree that "clean the regulator" makes no sense at all. With that many miles I don't think it's unusual to need some new injectors. Make sure you put in the "blue" spring mod as your injectors will love you for it. The regulator is on the front side of the engine mounted fuel filter. The spring is behind the little "T" shaped cover.

When I looked on ebay the picture of the fuel regulator was a about a 2in.long cylindrical with a 2 wire plug on the side near the top that screws in to the block, the part below the block was also round, 2in long and had holes along the sides with a screen on the very end. I also saw the blue spring fuel press reg upgrade kit and it looked totaly different, looked like what you are describing. to say the least i was confused thats why I asked where it was located on the engine. Thanks for the info. The only codes on my scan tool was uo306-ford software incompatible with ficm, need reflash. The ford tech said that would not have any effect on the miss in a warm engine.

The print out I got from ford didn't list any codes they found, only that they performed a multi point inspection and found injectors # 2,4,8 missing with #4 being the worst. I didn't go to ford for them to fix prob, I just wanted to know what was wrong so I could do the work, I think the tech just advised to clean regulator before I replaced injectors. I hated to take my truck to ford, the last time I took it was at 166,000 and they told me that the engine was completely shot/ruined/junk but they could patch it for 7,000 or put in a new one for 12,000.00. Needless to say I ran to get it away from there, now at 195,000 and several 3000 mi trips pulling HEAVY loads it still does'nt use a drop of oil or smoke and gets 18+mpg. I was at a loss about the miss.
