Kia Troubleshooting Questions? Ask a Mechanic
Have you checked the fuel cut off sensor yet?
I'm sorry, I guess I was thinking of the Sorento. It has one on the passenger side fender and is easily bumped when checking the air filter. On the amanti the fuel cut off is integrated into the PCM. Do you have a scan tool that can command the PCM to run the fuel pump?
So we'll have to do the testing the manual way. First, do you have 12 volts to the 20AMP fuel pump fuse in the under hood fuse box?
Do you have 12 volts at the fuel pump relay on pin 38?
Ok. Let me know how it goes.
I'm sorry, for some reason your question dropped to my timed out list and I didn't see your last response.
Shoot. I just looked at the diagram again and it looks like pin 38 should be grounded by the PCM to command the fuel pump relay to kick on. If you ground pin 38 with a jumper wire will the fuel pump run?
The pin on the opposite side of 38 (it's not labeled in the diagram) should be 12 volts. It is also on the same circuit as the injector power feed.
So then the PCM isn't sending the ground signal to run the fuel pump. You may need a scan tool to try to activate the fuel pump through the PCM. If it won't work then the PCM is the problem.
I think you'll need one to proceed. Otherwise you will never know if the PCM is doing what it's supposed to do.
