Where is the return less fuel pump located?
On newer vehicles with return less (EFI) systems, the fuel pressure regulator is located in the fuel tank. There is no fuel return line from the engine back to the tank. Fuel pumps run continuously once the engine starts, and continues to run as long as the engine is running.
How does an electric fuel pump pump work?
When the ignition is activated, the (PCM) energizes a relay that supplies voltage to all electric fuel pumps. The motor inside fuel pump starts to spin and runs for a few seconds to build pressure.
Why does my fuel pump not prime with the key on?
Fuel pump doesn’t prime with key on. I’ve been trying to figure this out for a couple days now. My 01 Tiburon wouldn’t start the other day. It would crank, but wouldn’t fire. When I turn the key to the “on” position, the fuel pump doesn’t kick on.
How can I check if my fuel pump is working?
Before you check your fuel pump, find the fuse that corresponds to the pump and pull it out to see if it is broken or burned. If it looks fine, check the voltage at the pump itself to make sure the charge that’s leaving the fuse gets to the pump. If this looks alright, then perform a fuel pressure test.
Where is the test point for a fuel pump?
Hook the pressure gauge to the fuel pump test fitting. Locate your fuel pump test point, which is usually near the fuel injectors, and locate the point at which the pump hooks up with the filter injector rail. There should be a separation joint or a test port, where the pressure gauge attaches.

Where can I get a fuel pump gauge?
Get a fuel pressure gauge. Commonly available at most auto parts stores for $20-30, a pressure gauge is a good investment, useful on most makes and models of cars. If you don’t want to buy one, you can also often borrow one from machine shops or auto shops who have them to lend.
