P0107 doggy top end?

[steve86]

Alright I posted before about this issue but since I hooked it up to scanner I found out I had codes but the check engine light never came on. So I had a p0107 a over boost a fpr and a rail pressure one sorry can't get the numbers but it was awhile ago been real swamped with work. Then I was climbing around the motor last night and seen the top of the fuel housing was moist wtf can't find a leak and plunger is hard as a rock truck runs solid 1 thro 3rd shift but beyond 2000rpm dogs down. So confused and don't know if this means anything but it seems like the truck run better in the am

 

[steve86]

Getting kinda irritated I dumped 2500 in new injectors and lines is running a lot better but only at 70% potential
Injector rates are great

What's the fuel temp sensor reading?

 

[DIESELMAFIAPER.LB7]

Sounds like your losing Rail to me.... turn the juice down see if runs fine stock?

 

[steve86]

Don't know the fuel temp I've tried to turn the juice off and it does help but trying to figure out why I can't run hotter tunes without it boggin

 

[steve86]

The mechanic that are the scanner said my pump is fine and my fpr is working told me to start with map sensors and then told me my maf was only reading at 166 wot and said that wasn't right my first diesel so I dunno

 

[DIESELMAFIAPER.LB7]

If turning it down helps I'd bet you need a lift pump have you watched rail pressure at wot? Also maf usually makes it doggie down low.

You have to realize your turning what 38s with that lift that's alot of mass

 

[steve86]

Am running 35s and I got a fast 150 lift pump. No I haven't clocked the rail pressure wot

level 5 still has a lot of get up and go even with that size tire. edge w/ attitude is all i had for a long while before and after my lift

Is your FPRV shimmed or a race plug?

 

[steve86]

Alright guys I went out and hammered down so I could get it to throw the codes I couldn't remember here they are p0380,p0106,p1093,p0090,p0540,p0193 OK so when you guys answer remember first diesel can one condition cause all of these or am I just screwed :violent:

 

[LWATSON]

Yes, one code can occur and cause others.

 

[steve86]

So can anyone point me in the right direction because I don't even know where to start am good at fixing just horrible at diagnosis

 

[LWATSON]

0087 is probably your culprit. Low fuel rail preasure, too much tune and not enough fuel.

 

[steve86]

I didn't have a 87 code. Am I missing something

 

[LWATSON]

You said in your opening post you had a rail pressure code, that's an 0087.

 

[LWATSON]

I'm sorry, you have an 02, could possibly have been a 1093?

 

[steve86]

Could any of this be from a bad filter

 

[steve86]

OK see if am on the right track truck runs a little better in the morning and worse in the heat fuel to thin? And the code is high pressure side

 

[steve86]

So the three I need to figure out are 106,193,90
