2004 hyundai sonata won't start


Asked by Sep 10, 2016 at 08:40 AM about the 2004 Hyundai Sonata Base

Question type: Maintenance & Repair

Hello all,
I have a 2004 hyundai sonata . Drove it to work a
week ago and ran fine. Got  in it after work and will
not start now.  I changed fuel pump and fuel
presure valve on end of fuel rail.
Still won't start.
I took the fuel presure valve on the end fuel rail off
and tried starting the car. It started but of course
gas was dumping out of the end of fuel rail. But it
did start. I put presure valve back in and it won't
start. The presure valve is new. Why would it start
with the presure valve out and not start with it in?
Please help. Thank you for your time.
