what’s causes fuel pump not getting power?

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Titan. If your fuel pump isn't getting power, it could be due to a blown fuse, a faulty fuel pump relay, or an issue with the wiring. The fuel pump relies on a relay and fuse to receive electrical power, so checking these components should be the first step. If the fuse is blown, it may need to be replaced, but it's also important to figure out why it blew in the first place—this could indicate a deeper issue, like a short circuit or faulty wiring. A bad ground connection or a problem with the engine control module (ECM) could also prevent the fuel pump from getting the power it needs. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
