Default 90 89' 5cyl fwd, car stalls once in 1-2 days, fuel delivery problem and

<center><img src="http://pictureposter.audiworld.com/44578/90box.jpg"></center><p>i've found out that when i release pressure from line that is connecting fuel pressure regulator to fuel distributor, car will start right away. (yellow arrow)

what can be the problem? car is idling now for 30 minutes. steady idle. and i think regulator must work all the time.

so what is causing fuel regulator to fail? any ideas?

it looks like its working when its working but when car is parked for longer time (10 hours give or take) it will fail within mile of driving.

P.S. i borrowed picture from L0rd of da rings. altough i have camera here with me. i dont have cable to transfer picture to my computer.
