I'm leaning towards an electrical issue with the fuel pump
Any pics would be appreciated

thats perfect
I was thinking about tying into the cage with a bushing since the cage never got tied to the frame
If you have a cage I would tie it directly into the slider.
I'm still baffled by this because even the FiTech directions note 58 psi for the 400hp kit. I wonder if that's a FCC output spec......
I might call in a bit and ask just to check. At idle with vacuum hooked to the regulator the fuel pressure is at 33PSI. They also said that was where it was supposed to be.
from FiTech's FAQ
What is the fuel pressure of the pump?
That is more the job of the regulator, on the Command Center the standard pressure is 4 bar or 58 psi. This is the Factory Preset for our Go EFI line of products. We offer 3 bar 43.5 psi replaceable regulators as an additional option for customers who might want to use the Command Center in conjunction with other brand EFI systems that may run a lower pressure. These regulators are easily changeable with 2 mounting screws and are available on our website under the ” Accessories” section.

My sliders tie into the frame on my F150 in 4 spots. 2x4" rectangle for the sliders and 2x4 for the braces. It easily supports the weight of the truck for jacking up with a hi-lift or when sliding off rocks.

A while back, Cody (one of the tech support guys from Fitech) used to be part of the user led fitech owner facebook groups and said this:
Go Street, Mean Street = 43 PSI
Here is what he said in full:

If you don't do facebook, or if you can't view until you are part of the group, I can paste the full text here, just didn't want to crap in the thread, as it is long.
I couldn't find it officially on fitech's site (which is a pain to find stuff on).
That's some pretty important info when troubleshooting just to leave out......
Im waiting to be approved to join the group.
FiTech puts alot of how to and update stuff on their facebook and nowhere else as if everyone that buys the product follows them. There are things on facebook that arent even on the install/owners manual.
I'm glad they finally did videos though......
Thats true those videos help set the IAC
I just find myself comprehending a video much easier than reading. Plus I'm a man and men don't read directions.

Yeah, they suck at at updating their tech articles, and manuals. Also making them so they are actually searchable.
I did call in one afternoon though and I was on hold for less than 3 seconds. That was nice.
Just got off the phone and the tech Mike said "the GO Street EFI (400hp) needs 43PSI and the 600ph needs 58"
I don't usually get put on hold only once for 35 minutes
I'm going to see if plugging the return, to see if fuel psi goes up. My fcc was putting out about same psi. But the gauge was on FCC. And it didn't always be at that psi. Only after driving a while it dropped. Then never would be up that high again. Maybe pump burnt out or fuel regulator is stuck open? I'm not even sure how the regulator works. Lol but I got mine running ok, will stumble a bit sometimes when I stop then snap the throttle or going under 25mph and snap into throttle. But my truck won't get over 150* and usually stays around 142* while cruiseing ethier. And that's in the hottest part of day 75* and at 7000ft+ elevation. I think at sea level and if I block the radiator some more will help it get up to running temp. I already have one 8" wide card board going from top to bottom on radiator and that got me to reach 150. Before it never got above 140. Sorry for putting do much of my stuff in your thread also. Not trying to hijack your thread.
You need to hit the 180 mark for the EFI to start learning. Will it not hit 180 at idle parked? Furthermore, if your registering only 140-150 on FiTech I think you have a bad coolant temp sensor which will cause all kinds of wierd shit.
