    Acc & On Circuit Relay

    Hi all

    The car was feeling a little slow on the top end. I installed a fuel pressure guage , changed the fuel pump to an AEM one and installed a new fuel filter.

    It felt better but not quite. I bypassed the fuel regulator solenoid and installed the factory fuel regulator directly to the throttle body.

    the car now at idle has 26-28 PSI , with AC ON 22-24 PSI , full throttle max boost @ 8 psi i have 32psi of fuel pressure ..

    some one recommend to change the alternator and damn that made a difference ... my fuel pressure at max boost is now 36 psi and the car feels much much better.


    now the problem that i am facing is that my fuel pump never gets more that 13 volts or any thing inside the cabin .. the cigarette lighter has 12.9 volts and the in car voltage regulator shows 13.3 volts but at the battery i get 14.4 volts

    i checked the fuse box inside the cabin .. only the always on acc list brake lights were getting more than 14 volts .. all other thing on the key acc & on position were at 13 or less volts ..

    is there some sort of relay that turn on the acc & on circuit .. i predict that their must some sort of corrosion on that relay or the relay it self is faulty
