Re: 2004 Grand Cherokee 4.0 cranks but will not start...

Before you spend money on it, verify that there is a DTC for a "CKP signal not received by the PCM" . The CKP is located on the upper section of the bell housing close to the engine where the starter ring gear on the flexplate. It's black in color with a wiring harness coming out on top of the sensor. Usually held in place with 2 bolts. When you get the new one, it might have a piece of thin card board on the tip of the sensor..Do NOT remove the cardboard. Install the sensor as is. It's there for the proper airgap of the new sensor.
