Starting Problem

[74trs]

I have a 98 Cherokee having issues starting at times it will start runs great shut it off then it just turns over no spark. Get irritated walk away from it for awhile and turn it over then it starts? Have changed the auto shut down relay. Could it be in the computer? I am not sure but i think it would either start or not if it was in the computer? Any suggestions would be great?

Thanks 74trs

Check the connector to the CKP for corrosion loose connector, possibly going bad.
