okay guys i hope you can help me im so stumped on this.
I have a 2005 subaru wrx with a hybrid swap dynamic 1000cc injectors, sti cams, sti crank, cosworth pistons, walbro 255 pump (new) invidia downpipe, and a couple little things. but heres my problem i got in my car just a few days ago started up perfect ran fine went down the road maybe 2 miles stopped at a house shut it off for 15-20 minutes came out will not start... so i tried plugs nothing i checked to see if i had spark i have spark. just replaced the new walbro pump saturday and i did a fuel pressure test it was reading 120 psi! which i know is insane amounts of fuel. i put the regulators on the driver side on just today and still nothing, but when i hold my gas pedal clear to the floor it does try to start but really rough and it'll just die. ive also put a cam and crank sensor on too. i've been looking for fuel pressure regulators that are adjustable but cant seem to find a good fitting one or anything else that it might be please help!
