HELP!!Fuel Pump

[DrFT_aLLDWay]

Help guys i have a screwed up problem

I think the fuel pump is stuffed.

The car starts and the fuel pump works for like a few secs then turns off which then the cars turns off

I took the fuel pump out and connected it to 12V and it works

What else could be the problem?

Does anyone have the fuses diagram?

Its a R32 GTST

Thanks guys..

Skyline fuel pumps run at a lower voltage when your foot is off the accelerator (ie, idle). It sounds like either the voltage is dropping too low, or the pump isn't as strong as it used to be and can't supply enough pressure at this lower voltage. Do a search on these forums, there is a method by which you can make the pump run at 12 volts constantly. That should fix the problem.

Just connect the negative terminal directly to ground(chassis), and this will make it permanently at 12volts. (at the plug)

The pump circuit has a floating ground that reduces the voltage to the pump at idle, maybe this part of your circuit is stuffed...

anyway do above and you will bypass it.
