The relay should have 4 pins on it. Connect pin 87 to the positive post of the fuel pump. It is important that the fuel pump is capable of the correct fuel pressure at full power, otherwise the engine could be damaged due to a lean.
Web The Relay Should Have 4 Pins On It.
Wire pin 85 to a good ground on the car. This will complete the circuit and allow power to flow directly to the fuel pump. They are usually labeled 30, 85, 86, and 87.
The Relay Should Have 4 Pins On It.
I use a 4 pin. A bad or failing fuel pump relay can cause drivability problems and issues with the fuel pump. When the haltech ecu wants to operate the fuel pump it will close the fuel pump relay, which will supply the fuel pump with 12v from the battery.
In This Article, We’ll Discuss The Basics Of How To Wire Up A Relay For Your Fuel Pump.
Web this video details how to add an electric fuel pump to your project. Pin 85 is the ground wire. Web **parts list in description below**in this video, i show how i wired an inertia switch and fuel pump relay into an electric fuel pump circuit.
We focus on making this modification along with a classic update kit, but the process wo. Wire pin 85 of the relay to the 12v supply wire from the stock ecu that you just cut. Web everything you need know explained in simple steps easy to follow:
Run A Wire From Pin 87 To The Positive Wire On Your Fuel Pump
So now instead of the stock ecu energizing the fuel pump, it will energize this relay. Connect pin 30 to the positive terminal of the battery. The pin 30 has a direct connection to the battery.
