Probably the leading source for fuel pump relay problems is an overheating relay which represents about forty percent of total problems with REL in vehicles. The most significant reason why the switch could be too hot is continuous service, excessive resistance in the electric circuit and insufficient ventilation around the relay. Over time this material can break down resulting in reduced performance and eventual failure. The fuel pump requires power from the relay and if the relay is bad, your engine will not run properly.
Electrical surges also play a significant factor in the failure of relays. As much as 25% research has been shown to fail from sudden voltage spikes that can be caused by engine cranking, or perhaps bad battery conditions. According to automotive technician Mark Jacobs: "Most relay failures are a result of poor electrical connections or heat, reminding us yet again how important it is to have your electrical system well maintained and kept clean." This statement also point out:- the most of importance thing that is Relay life depends on how it is cases insidea relay and Counter space.
In one example, just last year an automotive recall identified over 200,000 vehicles experiencing of engine stalls due to a manufacturer defect impacting fuel pump relays. Investigations revealed that the relays failed too soon due to heat generated by electrical overloads, thus proving the correlation of heat and relay life. The incident was a rude awakening for both manufacturers and consumers, underlining the importance of keeping an eye on vehicle sub-systems.
Insufficient maintenance techniques further add to the problem. The Automotive Service Association said routine maintenance can reduce the risk of those problems. As it is unlikely that firing the car up for 30 seconds will replicate the issue, testers might give ―TEST voltage spikes (back away from a running vehicle!) Technicians suggest checking relay connections and correct electrical power during regular reviews at intervals of about 30,000 miles. Keeping up with these preventative measures will help you avoid major performance issues like stalling, less efficient on fuel consumption and difficulty in starting.
Usually, the symptoms of a bad fuel pump relay are subtle at first. Drivers might have difficulty starting the car or notice that there is not power when they step on the gas pedal. If not fixed virtually immediately, these symptoms may also worsen and eventually lead to full on fuel pump failure which is going to require costly repair or replacement. In fact, repairing relay issues early may cost car owners up to 60% less than waiting for those faults lead to full failure.
To sum it all up, fuel pump relay failures are mainly caused by overheating and electric spikes. By arming themselves with the information they need about what causes relay issues, drivers can actively work to keep their vehicles running without a hitch. By performing regular maintenance checks and being in tune with the first signs of trouble, you can avoid the hassle and expense brought about by a busted fuel pump relay.
