Kia Troubleshooting Questions? Ask a Mechanic
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
In order to try and help you with this can you scan the computer system and see if there are any fault codes setting and also can you install a fuel pressure gauge and monitor the actual fuel pressure when it seams to be flooding out. Normal fuel pressure should be right at 45 to 51 PSI. Check these things for me and let me know the results and I will try and help you get this figured out.
Can you tell me what year and model your Kia is and have you tried cleaning the MAF (mass air flow) sensor ?
Okay then if you scan it are you getting any fault codes to set?
Something sure dose not make sense here for sure, no codes, proper fuel pressure and yest you are saying your fuel fouling the sparks plugs when it will not start?
I been doing some digging and came across this service bulletin that may very likely apply. have a look and see what you think. Copy and paste the link to your browser to open and view it.https://dl.dropboxusercontent.com/u/104923897/Hard%20start%20Mar%2013.pdf
Okay, it may be the issues here. Nothing else is making much sense.
Well something has to be being over looked here and I am out of ideas. I will open the post back up for you if you would like and maybe someone else has something different to offer.
Hello, do you have NGK Kia spark plugs in the vehicle or did you put aftermarket plugs in it?
