Cadillac Catera gas not reaching engine after new fuel pump and filter installation, battery also dead on Cadillac Catera

Some Cadillac Catera owners report experiencing issues with fuel delivery and battery problems after installing a new fuel pump and filter. These owners have noted that the fuel pump circuit may have been damaged during installation, preventing fuel from reaching the engine. Additionally, they report that a dead battery could indicate an underlying electrical issue causing excessive drain, which may also affect the fuel pump's operation. Some have found problems with the fuel pump wire connection between the body and the fuel tank, leading to power loss for the fuel pump. Furthermore, it has been observed that the fuel pump is typically energized only when the engine is cranking, necessitating a voltage test to confirm proper operation. Owners are advised to thoroughly troubleshoot the fuel system for potential issues such as clogged fuel lines or faulty injectors to ensure effective fuel delivery and address battery concerns.
