2002 Kia Spectra has no power to fuel pump

check fuses and relays --is it getting fuel --check fuel pump --fuel filter --getting spark--check ignition system -switch to coils --no power or not turning over --test battery starter alternator and connections

All I can suggest that you check that the pump is getting power after that check the fuel pressure regulator.

The pump relay should have four terminals. Number 2 is a green red wire which powers the pump from a 10 amp fuse. Number 3 goes to the pump. Number 1 powers the magnet in the relay and number 4 is the ground signal from the engine computer. If the relay does not engage on its own, one of these circuits is not working.
The injectors get power from that 15amp fuse which gets power from the main relay.
The problem could be farther upstream with the 25amp main fuse.

Try changing the fuel filter first. Then you will have to clear the code with a jumper.

Hi, sounds like your air inlet or may have torn or came loose from the throttle body. This will cause a lean operation of the engine. Open the hood and look for a big hose unhooked or loose from the engine, or perhaps the hose has cracked open. Please let me know if this isn't the problem or you have any questions.

The fuel filter is mounted under the vehicle on the right side, near the gas tank. Your best bet is to raise the vehicle up on jack stands to get a better view. Be sure to note which direction the filter is is installed before disconnecting any lines.

how to change a damper pulsation FOR KIA SPECTRA 03

Fuel regulator is bad. Replace the regulator and all should work just fine. That is what sends fuel

I had the same problem. I changed my fuel filter too.Your catalytic converter is clogged. I could put the pedal to the floor board and couldnt hardly pick up any speed. I could hardly make up a hill on the highway. Take it to a kia dealership and they will, they should replace it for free, they did mine and I didnt have a warranty. I think there is a warranty on that specific part. That's what it is though.
