Help Check engine light flash

So i just did a walabro fuel pump but i havent been able to drive it until today. when i stepped on the gas in 2nd gear it sputtered and the revs jumped up and down then the check engine light flashed 5 times and it hasnt come back sience. be aware im awating final tune so my car is only running 10psi is it just the turbo cutting out because i am reaching 10psi or is it something worse.

Thanks Nick

 

revs jumping up and down is not your set-up running on wastegate pressure, it's something else.

 

Like what??? IT was running fine before the fuel pump and after is when it started happening

 

misfire??:dunno:

 

its really weird it is running fine now i think ill just go to subsru tomorrow and get the code read

 

Honestly it could be a million and one things. your best bet it to get a cel codes pulled instead of guessing. FYI- the fuel pump installation is pretty straight forward and not likely to give you cels. do you have cobb ap or know someon that does?

 

just stop by any checkers or autozone and use their cel reader and look up the code on Nasioc/

 

sounds good thanks guys ill try it

 

Your not leaking fuel are you? There could be a possibilty that your leaking fuel pressure. Possibly the hose from the pump to the sender may be leaking.

 

Ill check that thanks thats a good idea i havent seen a leak but it could i suppose

 

Or do like I did, and just buy a decent code reader...they can be had for <$100

 

or do like i did. Buy a tactrix cable and install Enginuity and learn how to logg your car. With ecuflash and eginuity you can do way-way more than what you can do with 500+ dollar engine code reader. Just my .2.

 

make sure the fuel pump area was sealed all the way too, i remember having problems with that before with intanks and poor seals causing air to seep in

 

^^
Evap leaks throw a pesky light.

Make sure the fuel cap is tight?? hahaha (lexus dumbarse fix)

 

3 clicks to victory

 

so i checked everyhting over again and all things seemed ok check engine light hasnt come back since... really weird and i would buy code readers and stuff but i am buying PPG gears later this month so i have NO cash

 

PPG:yumyum: good choice. Straight cut?

 

yes Strait cut ftw

 

straight cut FTnoise

 

^^Nice

 

LOL:laugh:

 

Filed away for future use. Thanks.

Stuart.
