ok everyone says its easy but i cant get my fuel pump to turn on. Can someone please walk me through it and let me know where exactly you should put the relay and which wire should go where?? Im using a 5 prong but no matter how long i stare at the wire diagrams i cant make sense of any of it.
I have a 3rd gen 3sgte in my 96 gt, please i know many have done this but i cant find the info i need. |

Playing with the voltage of the fuel pump (reducing it) has no impact on the fuel injected into the engine. The fuel pressure is still regulated by the FPR. The flow of the fuel pump at low speed is still high enough to feed all the 4 injectors. The only reason why there is this "dual fuel pump speed relay" is to remove some strain on the fuel pump when full flow isn't required (idle, cruise, low load). The fuel pump will last longer in this case. Also, the fuel pump noise will be reduced at 9V and this is good for the driver.
But I don't think that fuel pump life (200k+ miles) or fuel pump noise at idle is relevant for a tuned and modded car. So, feel free to bypass this fuel pump resistor pack and run the fuel pump in full speed all the time. |
