Product Information

Taking precautions can eliminate the danger and relieve you of the problems we discussed earlier. Avoid Keeping Low Fuel In The Fuel Tank A connection or plug is located on the bottom of an electronically controlled fuel injector. With this plug, an electronic signal from the ECU is transferred to an electromagnet, which opens a nozzle to spray fuel.

Fuel injector circuit wiggle test can be used only with engine running (KOER) due to the fact the FICM determines injector circuit faults by monitoring low or high injector current. Wiring harness chafes can often be difficult to locate. If any wiring chafes are noted, repair as necessary and re-evaluate vehicle. In this situation, we will advise you to change the fuel pump driver module. We hope that it will resolve your problem. Symptom 2: Engine Misfires When the ECU driver circuit turns on, current flows to ground through the injector solenoid coil. Without this control of the current flow through the injector, the solenoid coil would overheat, causing injector failure. What is an injection module? The Duramax FICM (Fuel Injection Control Module) controls how the fuel injectors function by sending electrical impulses to open or close the valve. It sends 48 volts to the injector coil, allowing the valve to open and release fuel into cylinders. Duramax FICM Problems A failing fuel pump can cause an increase in engine temperature. You might have a fuel pump problem if your vehicle’s temperature gauge consistently shows higher readings than normal. Symptom 9: Acceleration IssuesImproved design - since the factory board fails from excessive heat and vibration, this unit features additional securing compound to help prevent it from failing the same way again in the future bit engine-control microprocessor (Toshiba)" (PDF). Semiconductor History Museum of Japan . Retrieved 27 June 2019. In 1920, Bosch created the first diesel fuel injector in response to rising fuel demand and prices. Introducing fuel injection to vehicles improved acceleration and fuel efficiency, making engines more powerful and fuel efficient. So here are some bad fuel pump driver module symptoms. If you face any of these, solve them on time. Symptom 1: Stalling Engine

So in this article, we will discuss 9 major fuel pump control module failure symptoms and also give some preventive measures.

When this happens, the injectors become slow and disrupt the timing of fuel injection and combustion. This results in the release of excessive smoke from the vehicle’s tailpipe.
