Does a faulty fuel pump module have any impact?

[RosalieRose]

Yes, a faulty fuel pump module has an impact, as it can cause the engine to stall and prevent it from continuing to operate. The classification of fuel pumps and the reasons for fuel pump module failure are as follows: Classification of fuel pumps: A fuel pump is a lightweight and compact pump, which can be categorized into three main types: inline, distributor, and unit pumps. A fuel pump requires a power source to operate, with the lower camshaft driven by the engine crankshaft gear. Reasons for fuel pump module failure: Poor fuel quality, the presence of impurities or foreign objects in the fuel, and a dirty fuel pump can cause these contaminants to enter the internal bearings of the fuel pump, accelerating bearing wear and leading to fuel pump failure. Not replacing the fuel filter for an extended period, a clogged fuel filter, and prolonged high-load operation of the fuel pump can also result in fuel pump damage.
