Where is the Cadillac Fuel Pump Control Module Located?
1 Answers
Cadillac fuel pump control module is located behind the right-side panel in the trunk. Below are the detailed descriptions: 1. Function of the high-pressure fuel pump: The high-pressure fuel pump compresses low-pressure fuel from the low-pressure fuel line into high-pressure fuel, which is then delivered to the fuel rail through the high-pressure fuel line. 2. Working principle of the high-pressure fuel pump: The high-pressure fuel pump consists of the pump body, intake valve (high-pressure fuel pump solenoid valve), pump piston, outlet valve (check valve, mechanical device), and the pump chamber formed between the pump body and the intake/outlet valves. The high-pressure fuel pump is mechanically driven by a square cam mounted on the camshaft, converting low-pressure fuel into high-pressure fuel. This conversion process mainly involves three stages: fuel suction, compression, and fuel discharge.
