I have replaced the fuel pump 4 years ago. Recently replaced & within 2 weeks I have same problem have power to pump so I'm guessing I have a bad fuel pump? Any help would be most appreciated. This car is a electrical nightmare horn is disconnected honks on its own, cruise control light on doesn't work, turn signals sometimes work I could go on

Verify that the CEL consistently comes on for 2 seconds and then goes out, when the ignition switch is turned to ON (Position II). If not, the ECM may be bad. The ECM controls operation of the PGM-FI Main Relay, which controls the fuel pump.

What brand? My boyfriend has been getting a lot of parts that he keeps having to return. Air tec fuel pump and Drive Works being 2.
