Hey folks.
I've recently assembled my precious and have run into strange starting issues. After being shut down for some time, it takes pretty long time to crank the car before it starts. Also while cranking it bubbles a bit and after that starts and runs without any issue. I have a strong impression that it's the Fuel Pressure regulator, because once started, I can shut it down and start it again with half turn of the key. Seems like it doesn't hold the pressure in the fuel rail after shut down. No other issues have surfaced, it runs fine on boost, no misfires, no erratic running whatsoever.
Thing is, I've changed the fuel rail during the rebuild, since mine had the mountings cut off for some reason. I haven't hooked up the fuel pressure gauge yet, don't have any available right now.
I'm thinking maybe get a new regulator altogether. I have two choices:
1)Bosch 0 280 160 575
2)Pieburg 7.22017.50.0
They aren't too expensive. The Bosch one costs marginally more.
Engine - AAN.
Any advice appreciated.
