GVR-4 Fuel issue

[92gsxecl1pse]

So, i was coming home from a friends house and ive been noticing that my car has been leaning out pretty bad. Well it started to chug and hesitate pretty bad. While driving i couldnt get past 20-25mph, It would backfire and hesitate. But when idle it would idle fine and rev all the way to redline perfectly fine. Then i heard my fuel pump start to make a whining noise *Eternal pump also*. I replaced the fuel pump last night, cleaned the fuel filter/rail etc. and its doing the same thing also making the same whining noise, as if there isnt any fuel getting to the brand new pump. I turned the pressure up on my FPR to around 50, and its still leaning out super bad and still hesitating.

Really need some help with this please.

Well first off when you say it's leaning out, do you see that with a wideband or is that just what you feel is happening?

Ive got a wideband, its the NGK AFX

Well if your hitting 50psi on your FPR, then you should have fuel at the rail then. Do you have a DSMLink, AFC, or any way to control the fuel other than stock? Do you have the stock turbocharger in there with stock injectors and stock fuel control? What is "leaning out" I belive you should be at 14.X for idle/cruise.

Is this only related to boost when you have issues?

I just recently got DSMLink but haven't got a chance to plug it up yet and for mods I have 16g, AFPR, 560 injectors, MAF, external 255 fuel pump. The car seems to boost fine, it will build but the car hesitates terribly. And at idle it leans so far out that my wideband just stops flat at 16.00.

would a clogged fuel line cause these issues?

Yes. Change your fuel filter.
