2005 Kia Optima will turn over but wont start

We replaced crank shaft position sensor. Everything is in time. Put it all back together and tried to start it all it does is turn over but start. Any suggestions

Answer this question I have this problem too

Is this a good question?

is your check engine light on? have you checked for any trouble codes with an OBD2 reader? why did you replace the crankshaft position sensor and check timing? your post needs more context, and there are other forums that may be more appropriate for your problem... for example


The car had check engine light on we had it checked and it said it was crank position sensor. We checked the kia forums with no help. thank you


Have you checked to be sure the sensor is properly grounded? Clean under the washers and add some silicon grease where the wire hits the ground lug. Look at the wiring diagram. I'm going to guess it's a black wire going to a lug in the near center firewall, but that's only a guess.

After clearing the CEL and replacing the CPS, is the car throwing another code?


Not throwing any other codes. Thank you for your input. If this doesn't work guess it will be going to a shop.
