No. A failed fuel pump will not cause a no crank. This may be a failed PCM (engine computer). Do you have access to a scan tool?
That will work just fine. (I have one of those also!) Connect it and see if it will display the pids.
Let me know,
Ok, sounds good. I will look for your reply tomorrow. Disconnecting the battery will clear any trouble codes (if the PCM is "ok". ), but if the PCM is "dead" then disconnecting the battery will probably do nothing. However the PCM may have died due to temperature. Letting it cool down sometimes gets it going again until it gets hot.
Ok. If the scan tool was displaying sensor data, then that is good. Tells me the PCM is at least being powered up. Did the Jeep just stop running one day while you were driving or did it just not start?
Send me the Jeep's VIN number. I want to look something up.
