b6t leans out when driving

[festivBS]

Found out I was testing wrong wire, fuel pump is getting a consistent 11.6v.

I put the stock b6t injectors back in and now it will barely idle, reads over 17.0 on the wideband and I can't even touch the throttle or it will die. Having trouble getting a new fuel pressure tester cuz my old one broke. But im running in circles now and have no clue what to do next.

Does an aftermarket fuel pressure regulator sound necessary? I replaced mine with an oem one

if its running that rich you might have a bad sensor somewhere that's causing a "safe" default

[festivBS]

Its lean. Not rich. Not enough fuel or too much air

[festivBS]

What sensor?

[kellen302]

disregard the sensor comment if it's going lean like that, you might have an obstrruction in the line, or the pump is just not pumping enough if an interior seal is going ugly
IIRC, these like 35-45psi of fuel pressure at the motor, don't quote me on that though

I ran a new 3/8ths braided fuel line and I have a 255lph walboro in tank. I've looked that up before and that is around the correct fuel psi but like I said, my fuel psi tester broke so I need to get a new one. And what seal are you talking about?

[kellen302]

pumps have seals and what nots in them, if a seal is bad it won't pump the best

Okay I can picture the area where I think the problem is. Ill look into that this weekend then post an update. Thanks!

[festivBS]

alright..

fuel problem is fixed and the car no longer leans out, but now the issue that im having is my turbo will not create any boost. My first thought was that the electronic boost controller im using wasnt set up, so i set it up this morning and that was not the issue.

As i am driving, i can floor the gas pedal and the car will zero out on vacuum and never go over .00 psi boost: at this point the car starts to buck a little bit.

I switched my stock b6t injectors back in and they seem to work better than the 460's i had

Check the waste-gate actuator arm. Very possible its stuck open.

Can u get vids? Sounds like a possibility ^

Not pertaining to the problem but if u go above stock boost make sure you gap the plugs down otherwise it will cut out. Make sure your timing is correct also otherwise it will give u problems too.

[festivBS]

Yeah I gapped them down around .037 and I will go check the arm right now! And yes I can take a video just didn't know how to post it on here. But I can get it to my PhotoBucket easy and send a link

[festivBS]

It works! the wastegate rod was positioned funky and was holding it wide open. I successfully hit 16 psi for my b6t swap's first time
