No Start and OBD connector location?

[Zarniwoop]

Hi All,

I'm starting to get a little frustrated....

My Australian right hand drive 2000 Kia Sporatge died in traffic a few days ago, just went peacefully. Now it will crank freely but will not start at all. So far I have checked:

-Timing belt ok, cam moves.
-Fuel pump ok, 12V at pump, 3A flowing to pump on crank, fuel from filter, replaced filter.
-Spark at no.1 and 3 plus, didn't bother checking the other 2.

I purchased an OBD reader hoping to get some codes but I cannot for the life of me find the socket for it under the dash. Someone kndly posted a picture for me of the location on 4x4wire but it's definately not there and I have also looked on a 1999 model and cannot find it on that either. There is a diagnostic port in the engine bay but I believe this is for shop based equipment. I also know that some models outside of the US changed over the OBDII later but I have tried the jumper method on the diagnostic port with no codes flashed back. The method described requires the engine to be running which is going to be tricky as it won't start.

- Does anyone know how I can either locate the OBD2 socket or clarify if it is OBD1 or 2? There is no sticker or plate in the engine bay to clarify this.

- Any ideas what I might try next to get the thing started?


Cheers

I followed your saga on 4x4 ; I'm just surprised no one from Australia came to the rescue as they are several regularly attending the show, probably with same configuration as yours. ...Since my 2000 is as shown on 4x4, I've no idea but if the plug under the hood fits the code reader, my guess is that is OK....mmmm...do I have also one under the hood in addition to the one inside?.....I'm gonna check that out....
....you said "it will crank freely" ....if I take that word for word, I would also doubt the timing belt ;.....checking for the timing marks or having a compression test done would make or break this hypothesis....
..what mileage does it have?
..and a pressure test on the fuel rail would also clear the fuel issue...do you hear the pump buzz for 1-2 sec when you turn key to ON the first time ?...it probably does because if it was blocked it would most probably take more than 3 amps..

Sadly the saga continues, the OBD reader does no fit the connector under the bonnet and I think that is a different protocol designed for the workshop computer? Anyway we spent the entire weekend probing the damn thing with an oscilloscope and comparing waveforms to another working sportage (nice thing to have around) and the only thig left that we couldn't test was fuel pressure. Off to the dealer with it and that was fine but the compression test revealed that number 2 and 3 cylinders were at ~55 psi compared to 1 and 4 at 85psi. No water in oil.

Right now I'm trying to work out if it's better just to get an entire reco. engine dropped in or go through the pain of removing the head in the hope that it's just the head but that will still cost a fair amount to get reconditioned. Ho-hum...

(On a plus note considering that I will be keeping the sportage for a good bit longer now I intend to put some time into building a converter to read the OBD codes from the plug in the bonnet, anyone got the pin outs for this plug and the ECM? - and preferably the entire ECM spec too )

WIth those "way too low" readings, next step inline is go for the timing belt. ALmost sure that is the problem.

Sadly already done .

Off the reconditioners on Tuesday....
