Kia Troubleshooting Questions? Ask a Mechanic
Do you have a spark? and do you have normal fuel pressure with the new pump installed?
do you have 12 volts on the connector for the fuel pump? Is connector tight?
On KIA's checking fuel pressure is tough because you have to connect inline with the fuel rail on the pressure side with the proper adapters.
If you have 12 volts but no ground it will indicate faulty computer or blown fuse for the computer, Sometimes when fuel pumps fail the amperage from the failure exceeds the capacity of the circuit and blows the fuse for either the fuel pump or the the ECM. You can use a computer safe test light to back probe the connector to check for voltage.
Sometimes if the fuse does not blow fast enough it will back feed through the ground side and damage the computer because the ground side is not fused.
Any parts outlet will have one.
You can use a regular test light, carefully, and don't remain on the circuit with the probe for very long just long enough to test for power and ground in a split second and you will be ok.
