Booster pump installed, NEED HELP-service light and questions

tampaturbom3 · 03-13-2015, 10:33 AM

I installed my Procede booster pump last night.
Trying to get the booster pump connected to the 2 hose clamps (1 large, 1 small) once inside the tank was a PITA. my hands are big and that fuel tank hole is small compared). Anyway, I got it all hooked up and back together. re-hooked up the battery and started the car (and it didn't blow up). It ran fine but i now have a little "service needed" triangle light on the dash and when I go to the Service section of the idrive, it says "fuel pump". It doesn't say it's failed or anything, it just says "fuel pump".
But driving seems normal and so I did a log on the OFT too. I will attempt to attach the CSV file here for those that know how to read them. CSV files won't attach. How can I put the log here for people to read?
What is "LP fuel" on the log? on my "before booster pump" log, it would drop down to slightly below 3000 and even one downward spike to 2200. on my "after boost pump" log, the lowest it got to was 5000 and mostly stayed between 5000 and about 5500. Also the AFR's are great (i think). The AFR readings on 93octane are sold 11.2-11.3 all throuh 2nd and 3rd gear WOT so i'm thinking if the booster pump wasn't working or there was a problem, it would show up here.
So it makes me think the service light thing is not a problem but just that the booster is putting so much fuel through it,, ,it thinks the stock pump isn't doing anything. is this possible?
if someone can email me so i can reply with an email with the log or logs (before and after) that would be awesome.
my email is tommygainer at eaglehm dot com

Thank you

Code out 2AAF iirc what ever the "fuel pump plausible" code is. That's normal, just means it detected a higher current coming from the fuel pump. It's just a nuisance message

^^^ +1 I had the same thing happen with my Stage 2 kit from Fuel-it, I then coded it out.

mine didn't send a SES light,,, it was just that little triangle... but after I got home from work, I noticed that the little triangle was gone,,, and when I went to the "service due" section of idrive, it said "all systems OK".. and the issue was gone.
I put 10gals of e85 in to have about a mix of e60... and no codes at all all the way home (30+ miles). I used to get the P29E0 and P29E1 anytime I ran anything more than about e25 to e30 (ironically the SES would pop up when cruising, not at WOT). so hopefully the booster pump is keeping the "lean" code away.
