I have a 2011 Subaru WRX (102,245 miles) that cuts out while driving. I bought the car with a lot of Cobb Stage 2 goodies. (Intake / Airbox, Cobb downpipe, Invidia Exhaust, Accessport). I turn the car on and let it warm up and it idles just fine, I wait until the car fully warm and then try to drive. Once I accelerate, the vehicle feels like its starving and sputters until it dies. I come to a complete stop, restart the car and it does it again when attempting to drive. Any suggestions??? I am thinking about making a makeshift smoke machine to see if it is a vacuum line. (I recently replaced the timing belt /water pump, turbo, oil) - but these problems were there before this changeout as well). Agitated as all hell. (I also have a IAG V3 Street AoS that I have yet to install- but don't what to install until the car is back to running correctly again) Thanks for your help.

 

Fuel pump; when was the fuel filter changed??

 

The fuel pump hasn't been replaced yet. What leads you to believe its the fuel filter/pump? I haven't experienced any hard starts, random misfires or rough idle. Rumbles as it should except when driving. Have you experienced this issue in the past?

 

Filter should be changed every 60K miles.
Have seen some bad filters videos using US pump fuel.
Maybe ask on NASIOC

 

ok, I am trying to find an in-stock FE0678

 

If you are looking to change the pump it's prudent to change the filter (item 6 below ) whilst it's apart.

 

I ordered a new fuel filter (#6) and ordered a new DW65c fuel pump. Should get the parts Monday/Tuesday. I watched Blakes Garage to show how the parts are installed. I hope this fixes all my problems. I want to get her back on the road. Thanks for the suggestions and help!

 

Great news everyone!!! I replaced the fuel pump and filter and I am no longer experiencing those stalling issues. Thanks everyone for the help!

 

Out of interest what was the condition of the main filter??

 

Fuel filter was ok I guess. It is plastic with only a little of the filter showing at the top. If you wind up replacing the filter. Drill thru the holes for 5 of the diagram. Aftermarket doesn't go on without hammering on or drilling. I should have chose the later and saved my self time. The filter on the Fuel Pump was a brownish instead of white, but there was no holes or pieces of debris in it. Hope this helps
