Ford Ranger 2.2 P2291 Error: Vehicle Won't Start Without Quick Start - Possible Causes

Model: Non Start Fault Code: P2291 Posted: 2023-12-02 08:20

I own a Ford Ranger 2.2 with a persistent starting issue. The vehicle will not start on its own and requires spraying of quick start to initiate ignition. It consistently displays fault code P2291. I have already replaced the fuel injectors and fuel rail from another running unit, but the problem persists. While it runs smoothly after using quick start, this indicates a deeper underlying issue. What other potential causes could be responsible for this non-start condition? Any insights or diagnostic steps would be greatly appreciated.
