What would cause an ECU fuse to blow?
Fuel Pump. Another cause of an ECM 1 fuse consistently blowing is a fuel pump problem. When the fuel pump begins to fail it overheats, causing it to drain more amperage (amp); if the amps exceed the amount of amps the ECM 1 fuse allows, the fuse will blow.
Is EFI the fuel pump relay?
In most vehicles, the fuel pump relay can be located in the fuse box in the engine bay. Your electronic fuel injection (EFI) main relay switches on the EFI computer system when you turn your key. This readies the injectors and pressurizes the system before starting the engine for startup fuel delivery.
Does EFI control fuel pump?
It uses engine RPM and signals from different sensors to meter the fuel. It does this by telling the fuel injectors when and how long to fire. The ECU often controls other functions like the fuel pump and ignition timing.
