P0093 and P008A

Kallbmrt27c · Aug 8, 2015

Hey guys,
Threw p0083 and p008A this morning on my way to a race.
It kept consistently throwing the truck into limo mode. I just did something's to the truck and wondering that had a effect. I have had any issue with it before until this morning
1. Changed fuel filters about 3 weeks ago
2. Egr ****** this week
3. Filled the truck up with fuel this morning.

I disconnected the hard fuel line behind the egr when I ******d it in Tuesday. I made sure I tightened all the fitting when I finally got it out. Didn't notice any issues until this morning with it. I've been driving the truck pretty hard for the past week since I ******d it. I'm running a mini maxx and the fuel pressure was reading 4k psi at idle and 21k psi when I tried getting on it and it would Throw the code.
Any help would be appreciated guys, I'm trying to get up to a motocross race this weekend

Did you unplug the butterfly valve after the intercooler ?

Yes I did, black rectangle with plug on the bottom?

I took that fitting apart on the hard fuel line behind the egr, I didn't know if that was like a 1 time fitting type if thing. I figured I would have known right away after I ******d that if that was wrong. Like I side I had no issues until this morning.

Try a fuel system priming. Cycle the key to on, don't start, wait til pump turns back off then cycle again. 5-10 times is plenty.

I tried that. I would get a few miles down the road and it would throw the code again. Tried opening the bleeder on the LPFP and would here some air come out before the fuel. I never really noticed if it did that before
