My wife recently purchased a 99 Sportage. It ran fine for a few weeks, then began an intermittent miss. I changed the plugs and wires, and solved the problem.
About a week ago, it died twice while driving. Took a couple of tries, but it started. I drove it one day and it ran fine until I shut it off - would not start. Finally got it started with carb cleaner in the intake. Ran fine the rest of the way home, shut it off, no start. It will start occasionally on its own, but usually I have to spray it.
This is my first post here, but I have been reading a lot. Here is what I have done so far: cleaned throttle body, cleaned IAC, replaced two cracked vacuum hoses, replaced the negative battery cable, ran an extra ground from the battery tray to the fender, cleaned the ground at the ECU, checked the fuel pump and main relays, check good (haven't been able to find replacements yet), checked all fuses. I have an AutoTap, so I pulled the codes: P1693, P0446, P0116, P1614, P0561. These codes come and go, CEL is not on. Strange thing - Key on engine off, the realtime readings tell me 15% Calculated Engine Load, Throttle Angle is 10%. Could it be the TPS that is causing all of this?
I tried to change the fuel filter, but could not get the fittings apart. I haven;t been able to check fuel pressure because I can't find the port. Manual says it is next to the regulator, but it's not unless I am blind. Tomorrow I will try to check the fuel pump and grounds there.
Those codes you posted are signs of poor connections - you've done a fair amount cleaning up terminals and connections, so all I can suggest here is go through and see if there's any you've missed - how about the chassis to engine ground.
It would of course be good to get the fuel filter changed, but you mention that it runs fine once you've got it started would lead me to believe that the filter is not your problem.
The pressure tapping point is usually on the fuel rail or the pipe leading to it, but one of the Sportage owners will confirm this.
If the TPS sent a signal representing a position different to "closed" I can't see how it would interfere with the starting, after all you can start an engine with your foot on the throttle. A bad connection on the TPS is one of the typical problems, and some have resorted to soldering the wires to the TPS.
What plugs did you use, and what gap - it's know that the standard NGK are best and should be gapped at 0.75mm (0.03") and not 0.044" as stated in Kia litarature.
In addition the the throttle body and ISC that you've cleaned, I would do the same for the EGR valve.
Have you had a look at this site KiaTech - registration is required, but free.

Ron, Thanks for the quick reply. I can't remember what brand of plug, sure it wasn't Bosch. I am sure I gapped at .044 though. The only ground I have found so far from chassis to engine is at the battery tray. I would like to change the fuel filter too, but looks like someone before me boogered the connectors. Do you push toward the filter, then squeeze and pull off? I may end up replacing the fuel lines at the filter.
If anyone can point me to the fuel pressure port, I would be very grateful.
I have subscribed to KiaTech. I'll check the TPS connector, and clean the EGR.
Three things I'd check are the fuel filter, looks like the person before tried and may have given up, if I remember you have to push the connector in towards the fitting first, kia has a special tool because it can be tricky and can bust a fitting. check the plugs to see if there is oil around the last two which tends to ground them out, and all the electrical connections. The Sportage engine is known for it's poor connections, get a small brass wire brush and a can of contact cleaner and go around and clean all the connectors you can find, be careful when doing the MAF.
How old is the timing belt, they are known to stretch and slip a tooth.
That is what I was trying with the fuel filter, but no luck. I may try it again or try and buy the two lines. No oil around the plugs, tag under the hood says timing belt was changed at 88000, now has 140000. I'll give cleaning the connectors a try. I tried running a ground directly to the fuel pump but didn't help. I unplugged the connector on the pump and replaced it. It started and ran about 5 minutes, then shut off. I cannot hear the fuel pump run when turning the key, but it will run if I jumper it under the hood. What controls the fuel pump relay?
The ECM controls the fuel pump relay.
The objective being to only run the pump when needed, so when the ignition is switched on the pump will run for a number of seconds and if no ignition pulses will stop the pump. While ignition pulses are present the pump runs continious.

Finally got back to working on it today. Tried again with the fuel filter, still can't get the connectors loose. I was going to pull the fuel pump and clean the filter on it, but the screws started stripping, so I stopped for now. I checked the resistance on the fuel pump relay contacts, got 8 ohms, cleaned the contacts. I started cleaning all the connections I could find with contact cleaner. No luck with any of it, and it would only run as long as carb cleaner was in the manifold, before it would start and run fine. I decided to check the spark, so I pulled off all the intake back to the throttle body, pulled a spark plug, cranked it and it tried to run! As I put it back together, I started it after each piece, and it ran each time. After it was all together, I let it run until it was warmed up, shut it off, and restarted it. Shut it off, and it wouldn't start. Got it started again, wiggled the wires at the MAF sensor, and it shut off. I checked the wires - ground is good, power is 6.5V, two wires to the ECM check good. I haven't been able to find any wires frayed or damaged. Does anyone have any ideas? PLEASE!
