2001 Kia Rio fuel pump problems.....
Ok, quick question. 2001 Kia Rio. At times the fuel pump does not kick on when the ignition key is turned on. The fuel pump will eventually come on after cycling the ignition anywhere from 3-8 times. We've already replaced the fuel pump relay. Is it definitely a fuel pump problem or is there any other component that may be keeping the fuel pump from starting? TIA and hope my question is clear. And if the fuel pump, how bad is it to replace on these cars?

Most in-tank pumps are PITA's, but some have an access hatch that avoids having to drop the tank. The actual pump replacement is fairly simple. Next time it happens try banging on the tank with a big mallet or biece of 2x4; if pump then starts running that's another strike against it. Loose connectors can also give you intermittent operation, but most often it's simply the pump.

Ok, even if it's turning over strong and everything else works fine? It's just that sometimes it takes a few turns of the key for you to hear the fuel pump kick on. I just don't want to replace the fuel pump if it may be something else. TIA!

Ok, thanks all for the input. Very intermitttent problem. Would work fine for 3 days to 2 weeks then go out for a few times. Went ahead and replaced the pump tonight. There was an access hole right underneath the back seat. Of course we didn't find this out till we spent 40 mins working on getting the tank partially dropped. Oh well, got the tank back up and then it only took 20 minutes to swap out the pump after that. Hoping this takes care of the issue, especially since the pump relay's also been replaced.

obtain a wire diagram and at the relay, backprobe the wire that comes from the computer (it should have 12 volts for a2-3 seconds) with a test light to ground. if the light lights every time and the fuel pump doesn't run, it's not the computer. then it's probably the ign switch...
