Mazda Tribute starting issue after cold weather with recent battery installation and replaced fuel relay on Mazda Tribute

Some Mazda Tribute owners report experiencing starting issues after cold weather, particularly following recent battery installation and fuel relay replacement. These problems may stem from a malfunctioning IAC valve, which can cause stalling after a cold start. Additionally, owners have noted that replacing the battery and alternator can lead to starting difficulties, where the engine turns over but experiences a pressure drop, resulting in stalling. Some owners find that their vehicle only starts with starter fluid, which may indicate deeper fuel system issues, despite the inertia switch, relay, and fuse to the pump functioning correctly. Furthermore, the Passive Anti-Theft System (PATS) may inadvertently prevent the car from starting if it fails to send the appropriate "enable message" to the powertrain control module. In cases where the car starts only after multiple attempts or with starter fluid, even without check engine lights, it often suggests that components like the fuel pump, fuel filter, and injectors have been replaced without resolving the issue. Owners are also advised to inspect the fuel filter for clogs and verify fuel pressure stability across various engine states to effectively diagnose and address these starting concerns in their Mazda Tribute.
