Fuel pump problems? - SRT Forums

berkdog84 · 10-29-2009, 05:29 PM

I was driving around last night and the car died on me.
now its being a pain.
now...
--Fuel pump will often not prime..
--car will die at idle some times (say if I'm sitting in the garage with the car running while filling block with coolant)
--car hits a wall when i get on it even a little bit bucks then may or may not die when i return to normal driving.
--car dies at normal driving intermittently. (on the freeway on the streets cursing)

I am on aem ems so NO codes.
I also already swapped the relays.

Ok so i put in stock computer and stock injectors. now the car idles extremely lean. but now the pump primes all the time lol.
fired up sits at 14.9 for a sec then 14.0 then just keeps raising tell it reaches 18 with in about 10 sec of car being on. what is going on!? no exhaust leaks and my widedand was functioning as of last week with comparison to a dyno sniffer (.3 difference really but you get the idea).

did you re-wire o2 #1 in for the stock computer

Ok I guess I should clarify. I broke the motor in on stock computer and injectors with out a problem maybe a month ago, and nothing has changed with my set up since then.
So its not my stock computer being unable to keep up with my set up (at no load no boost idle) if that's what you are implying.
