Hello Dear Friends of Yo Reparo. I had my Grand Cherokee 97, 4.0, 6 cylinders repaired because it turns on but does not hold. They handed it to me, taking it for granted that it was already fine, but it kept giving the same fault. I returned it for review again and it was reset, that's what they told me. I reconnected it, but now it is heard that the starter tries to start and then, and therefore, does not start the engine. Because of this, the technician came to my home where my jeep is located to verify this “drop” of the computer and said it is the Krank Sensor, I told him that when it is the CKP the starter is dead and no matter how much you try to start it There will be a signal or noise that you want to turn on or be totally dead until you have a NEW CKP. So he told me that the CKP fails because it heats up and if it is allowed to cool for a while or it gets cold, it works again by starting the car. In addition to the new CKP that are purchased in the refactionary are coming out defective and therefore it is better to get them second-hand but original. This explanation of the technician is because I told him that the CKP just put it NEW. And it remained to sell me an original second and so we would see that it is not that the computer is still defective. NOTE: I took videos of before taking the computer to repair. Also when they gave it to me for the first and second time of the computer repair shop. Well my friends, please I need your help. I appreciate your attention. ZIRAN
