How can I tell if my Hyundai Sonata has a fuel pump problem?
One of the quickest things to check if we suspect a Hyundai Sonata fuel pump problem is the activation relay. Every time you turn the ignition on or to the run position the pump becomes energized. On this page I have supplied a component location diagram pinpointing the location of the fuel pump relay.
What to do if your fuel pump is not working?
Check out your vehicle’s service manual to find out where to check and the proper procedure for checking it. Test for source voltage, to determine whether or not the good charge that’s leaving the fuse is getting to the pump. If no power is making it to the fuel pump, then check the fuel pump relay circuit.
Why is the fuel pump relay not turning on?
The ECM controls the fuel pump relay and this relay will only energize when commanded on. Does the check engine light come on; if not, then the ECM is not turning on. Do all the other combination meter warning lights come on?
How can I check the voltage of my fuel pump?
Check the voltage at the pump itself. Just because you’re getting juice from the circuit doesn’t mean that it’s getting to the pump itself, which makes it important to check the voltage there as well. Check out your vehicle’s service manual to find out where to check and the proper procedure for checking it.
How to check fuel delivery in Hyundai Sonata?

Which is the best Hyundai Sonata to buy?
The Sonata was named Kiplinger’s Personal Finance “Best in Class” in 2005 and 2007 and Consumers Digest “Best Buy” in 2006. Check fuel delivery in the Hyundai Sonata if the engine runs rough, stalls in traffic or doesn’t start at all. Relieve fuel system pressure.

What should I do if there is no power in my fuel pump?
A test of the battery with a digital tester that provides current voltage, cold cranking amps, and state of health should be done first. The battery is the heart of the electrical system and if it stumbles or fails, it can affect all other systems.
