So, can a bad fuel pump relay cause misfire<\/strong>?<\/p>\n\n\n\n Well, the fuel pump relay provides power to the fuel pump, any problem with it can cause a hindrance to the flow of fuel to the engine. In short, a bad fuel pump relay will create issue to the ignition which may cause engine misfires as well.<\/strong><\/p>\n\n\n\n A bad fuel pump can’t provide substantial pressure to the engine to run poorly and misfire it with wavering acceleration. The best way to fix a bad fuel pump is to get it inspected by a professional service personnel and let him do the job. <\/p>\n\n\n\n Experts recommend replacing a faulty fuel pump relay with a new one as the best way to deal with it.<\/p>\n\n\n\n Our thorough research on this point will help readers understand the issues related to fuel pump relays in a better and simple way. Herewith are the points that we are going to cover in this article.<\/p>\n\n\n\n Without further ado, let’s jump on to the sections.<\/p>\n\n\n\n Yes, a bad fuel pump relay will have issues with the ignition and result in engine misfires. A faulty fuel pump relay will also cause uneven idling plus stalling of the engine.<\/em><\/p>\n\n\n\n The fuel pump gets power from the fuel pump relay. If the fuel pump doesn’t receive any power from the fuel pump relay, it won’t function. Any malfunctioning of the fuel pump relay will cause problems with the fuel pump, leading to several troubles affecting your car’s drivability<\/a>.<\/p>\n\n\n\n One problem which you can notice is the misfiring of the engine<\/a>. A bad fuel pump relay cannot provide substantial pressure leading to engine misfiring. Before blaming the misfiring entirely on the faulty fuel pump relay, you can also check for depleted spark plugs and faulty wiring.<\/p>\n\n\n\n Herewith are a few symptoms to identify a bad fuel pump relay.<\/p>\n\n\n\n If you notice stalling of the engine unexpectedly, it may be a symptom of a bad fuel pump relay. The faulty fuel pump relay cannot supply power to the fuel pump, indirectly stopping the fuel supply to the engine and leading it to stall. <\/p>\n\n\n\n After a while, you can start the vehicle with a partially faulty fuel pump relay but won’t be able to do in the case of an entirely faulty fuel pump relay.<\/p>\n\n\n\n A bad fuel pump relay will leave the fuel pump dormant without providing it the power it needs to supply fuel to the engine. You may still notice the cranking engine noise while starting the vehicle, but the engine won’t start as it doesn’t get an ounce of fuel. <\/p>\n\n\n\n Engine not starting may be caused due to several other reasons, so it’s inevitable to get your vehicle inspected by a professional mechanic<\/a> to identify the real reason.<\/p>\n\n\n\n If you become all ears while starting your vehicle, you often hear a low noise of whine or hum. This noise comes from the fuel pump whenever the fuel pump relay passes power to it to awaken it. <\/p>\n\n\n\n If you hear no noise, it could be due to a bad fuel pump relay. It happens when a bad fuel pump relay doesn’t provide power to the fuel pump, which won’t work without power and remains silent.<\/p>\n\n\n\n A bad fuel pump relay will affect the fuel pump to supply uneven fuel supply to the engine. As the engine lacks the appropriate fuel quantity, you may experience rough acceleration while driving the car<\/a>. This situation will eventually lead to stalling the engine to stop the vehicle. Later, it may happen that the car won’t start at all.<\/p>\n\n\n\n![\"Can](\"https:\/\/mindofmechanic.com\/wp-content\/uploads\/2022\/12\/Can-a-bad-fuel-pump-relay-cause-misfire.webp\" "\\"Can-a-bad-fuel-pump-relay-cause-misfire\\"")
