2002 Ford Focus ZTS P1237 Diagnostic: Engine Light On, Stalling After Fuel Pump and Filter Replacement

Model: 2002 Ford Focus ZTS Fault Code: P1237 Posted: 2012-07-18 14:30

I recently replaced the fuel pump and fuel filter because my 2002 Ford Focus ZTS would not start. After the replacement, the car starts and runs, but the engine light remains on with a P1237 code. Additionally, the vehicle intermittently stalls while driving. I'm seeking advice on how to diagnose and resolve this issue. Any insights into what might be causing the P1237 code or stalling behavior would be greatly appreciated. Willie.
