I have a 2000 Kia Sportage. She cranks but will not start. This is sudden and unexpected. This started about a week ago after I went to a Circle K. She started fine when I left my mother’s apartment and she started and ran fine after I left the first Circle K. When I came out of the second Circle K and tried to start my car she would not start. She cranked and initially acted like she was going to start, but then quit immediately. I had no problems with the car starting or running before then and there were no warning signs. I thought that the fuel pump might be the problem and went out and bought the parts for it and replaced the fuel pump and the strainer just yesterday. I have tried to start it again on several occasions since then, but still nothing. I am stumped as to what it could be and need help in figuring out as to what it could be. She acts like she is not getting fuel and that is why I replaced the fuel pump and strainer. If anyone might happen to have some ideas as to what could be causing the problem and as to what I should be looking at and testing, then please let me know as I cannot figure it out.
The problem might be with the crankshaft position sensor.
If the computer loses the signal from this sensor, the computer see’s no reason to operate the ignition/fuel systems.
How do I find out if that is the problem without replacing it? I don’t want to buy a new Crankshaft Sensor and then find out that, that is not the problem. Is there a way to test it without replacing it to see if it is the culprit?
Do you own a scanner that’s capable of doing real-time monitoring?
If not, then you can’t determine if the crank sensor is working or not.
So, the only alternative is to replace it.
I have one that will read the OBD 2 codes, but there is nothing showing in the codes. That is the only tester that I have besides a multimeter.
A failed crank sensor will not always set a code.
That’s the frustrating part of determining if it’s a bad crank sensor.
Can it be tested with a multimeter to see if it is good or bad?
The quickest thing you can do is measure the sensor’s resistance
If it’s just barely out of spec, it may in fact be okay
But if you measure 5 megaohms, for example, that sensor is definitely bad
I would also check the valve timing to see if the belt jumped or not.
