So I was right all along.
I had this exact problem but you were slowly feeding us scraps with the mods, car type, etc then smartassed me about "reading your scaps" so I gave up helping.
Anyway, glad its solved. Next time you post a thread, post absolutely everything about the car.
Not - "fuel pump maxed out"
"can't be, it's a nismo"
Well, it was, and yes, it was maxed out. Due to low voltage.
