I posted this but don't see it - I'll try again.
I have a 99 Kia sportage 4wd that won't fire. I couldn't see the crankcase sensor, which I thought might be the ignition killer, but the 4wd transfer case also has a rotary voltage generation sensor on it. I tested that and it's infinite ohms on all terminals. I know the crank sensor behind the bell housing will kill ignition (except I can't see the darn thing - if anyone has a Good picture it would be appreciated - I don't have a lift and it's tight going ;') However, will the sensor right on the back of 4wd transfer case also kill ignition, or should I just try to find the crank sensor? It's easier to get at the speed sensor on the xfer case, and it's a cheaper part, so I'll try replacing it first, but only if it's a start-killer ;') The starting problem is oddly temperature dependent. It started fine below eighty degrees, but not above. Oddly, when it got really hot, such as the engine was running for awhile, or outside temp was over a hundred degrees, it would start okay (I live in AZ - kinda hot here ;')
I took off the sensor on the back of the transfer case, cleaned it, then it started in all temperatures for two days. Now it won't start at all and I"m getting infinite ohms on all three leads of the xfer case sensor. I guess I got it working just enough for it to finish failing. However, if that sensor has nothing to do with killing the start, I'll go for the crank sensor back of the engine (If I can ever see it.)
I put the sensor back in behind the xfer case, and on a cool evening it started, so I guess that part doesn't affect starting if my infinite ohms reading was correct.
Which means I'm back to the crank sensor if my reasoning is correct. I'll try that but my main problem is I can't seem to find the darn thing. It's supposed to be behind the bell housing. Not much clearance underneath and I can't see it from up top. And I can't find a Kia manual in town to save my soul. Of course, the car decided to quit just when I have job training to go to and I don't have time or money go to a shop or get some wheel lifts and fiddle with it blind. Anyone got some really good pictures or IPBs showing where this darn thing is? Also, is it easy to get off? I saw a note that it has some wierd nut that's hard to get at and I don't have long arms.
tks ahedatime for advice.
