Abstract
A vehicle fuel pump power management circuit that replaces traditional relay and fuse-based power routing with a MOSFET-based circuit controlled by the Automatic Shutdown Relay (ASD) and Engine Control Unit (ECU). The MOSFET circuit allows direct current flow from the vehicle's power supply to the fuel pump, enhancing reliability by reducing mechanical failures associated with conventional relays. A multi-layered PCB design minimizes electromagnetic interference, enhances heat dissipation, and prevents component overheating, while isolating circuits for optimized performance. The ECU provides real-time adjustments based on sensor feedback, ensuring efficient fuel injection timing.

A vehicular bypass circuit board for bypassing a fuel pump relay, fuel pump relay fuse, and fuel pump fuse, comprising:
- a. a plurality of printed circuit boards,
- b. an automatic switch configured to route power flow directly to a fuel pump's electric motor based on control signals received from an automatic shutdown relay;
- c. with the automatic switch being connected to and toggled by the automatic shutdown relay,
- i. wherein the automatic shutdown relay is configured to receive engine control unit signals;
- ii. wherein the automatic shutdown relay enables or disables power flow through the bypass circuit board to the fuel pump's electric motor in response to engine control unit signals.
