Fuel starvation? Sounds like no fuel in the engine then you back off and the pump pushes fuel in so it's fine. What mods?

Try replacing fuel pump. Or atleast make sure ur tuner has a fuel pump instock. So if it is the problem when he starts tuning he can replace it.

That^.

Tuner will hopefully be able to identify the issue during the tuning.

decided going to get injectors so may as well do pump as well. any other possibilities it could be?

LOL, sounds very simlar to my problem! Have a look at my thread: http://www.skylinesaustralia.com/forums/topic/360082-intermittent-fault-no-one-knows-what-it-is/

Does that sound like it?

I have 3 suggestions:

1. Fuel pump on its way out. I replaced mine but it gave no warning it was going to go. It was driving just fine and then one night it just wouldn't start. Unlikely to be this.

2. Intermittent wire short which is cutting power to the fuel pump. I just had this fixed on mine. Eventually it started blowing fuses. The problem started out like yours but got worse - only thing is, I'm not sure if I actually had 2 separate problems to begin with - one like yours, and the other with the car stalling randomly - or whether one caused the other. The short turned out to be near the O2 sensor - the wires running near the little heat shield. Don't know if yours could be these too?

3. Air flow meter. I suspect mine is playing up. Have a read of my thread to see the symptoms. This may have been caused by problem 2.

Let us know if/when you find the problem!
