What are the symptoms of a bad fuel pump driver module?
Symptoms of a failing fuel-pump driver module all manifest in the performance of the engine. Difficulty in starting or a smoky start-up, stalling or uneven running while idling, hesitations and misses when driving, and power surges when in reverse can all — separately or together — be indicative of a failing module.
How do you test a fuel pump control module?
STEPS TO DIAGNOSE: CONNECT PIN1 (BLACK GROUND) TO PIN16 (PINK GROUND) CONNECT PIN32 (RD/WH BATT + ) TO PIN47 (GY FUEL PUMP 12+) THIS WILL POWER THE PUMP TO RUN AND CHECK FOR A FAULTY FUEL PUMP. NEXT, CHECK FOR FUEL PUMP SIGNAL AT THE FUEL SYSTEM CONTROL MODULE. FIND THE DARK GREEN/WHITE WIRE IN PIN13.

How do I know if my high pressure fuel pump is bad?
Symptoms of a high – pressure fuel pump failure are: Delayed start of the engine. Hesitation or sputtering in acceleration between 2000 RPM to 4000 RPM. High engine temperatures. Vehicle stalling due to exertion or temperature. Fuel pressure gauge reading low measurements. Poor gas mileage.
Does a fuel pump control module have to be programmed?
The fuel pump control module must be programmed with the proper calibration software. The module stores and utilizes this information however if it is not properly configured with the correct calibration software, the fuel pump control module will not control all of the vehicle features properly.
Does the ECM control the fuel pump?
Some electric fuel pumps are controlled by the ecm and most cars have eliminated this problem by having a switch that keeps the fuel pump shut off until the engine builds up oil pressure. If you have a car ecm with an electric fuel pump and you suspect fuel problems, do this.
