fuel pressure problem. I have replaced everything now what? So the car is hard to start. If you prime it 3-4 times, it starts right up.
BUT.... It runs very lean. The long term fuel trims are at 25 across the board.
I have replaced the Fuel pressure regulator, the fuel filter, the fuel pump, the sock filter. also tried cleaning the ground wire.
Whats left guys? I'm about ready to junk the car at this point.
The FPR fixed the fuel trims but only for a short time. but it didn't change the hard starting.

So what is your actual fuel pressure ? Would make more sense to test that before replacing parts.

Your fuel is bleeding off somewhere...if it isn't outside the tank (which you'd likely smell), I'd look inside at the plumbing around the fuel pump itself (like the flex-line that connects the pump to the tank outlet). Looks like you've covered pretty much all other bases, but you'll need a fuel pressure gauge of some sort to properly diagnose this one.
