With all these different symptoms, I would start looking for a bad earth connection. Check all earth connections starting at the battery earth. Softails are inclined to corrode all the connections behind the rear wheel splash plate (behind the oil tank). Also, I have seen the wiring loom damaged under the seat right beside the battery connections. The cause of this is usually a non Harley battery with longer than stock connections and they rub against the loom shorting into it. This in turn can and has damaged ECU's.

2001 Grand Cherokee turns but does not run. Dash lights/ alarms stay on when it does start/ with no gauges working. Next day all is well.


Try pulling the error codes. You do this by turning the key in the ignition on & off to the start position, 3 times. The odometer will flash any error codes. This will help identify what is wrong.

Yes.
The speed sensor in the transmission gives the computer data to control fuel mixture and timing, and it also drives the speedo and odometer.
The sensor would need to be tested.

ENGINE WILL NOT TURN OVER/SPEEDO AND TACH LIGHTS FLASH


Hi Anonymous, and the usual suspects are:
1.Ignition/Light Key Switch not in IGNITION position.
2.Engine Stop switch in the OFF position.
3.Discharged battery, loose or corroded connections check negative cable at both ends. (solenoid chatters).
4. Bank Angle Sensor tripped and Ignition/Light Key Switch not cycled to Off and then back to
5. Starter control circuit, relay or solenoid faulty.
6. Electric starter shaft pinion gear not engaging or over-running clutch slipping.

Bad pcm speedometer death odometer freeze engine won't stay running for more then 2 sec


You replaced the BCM with a junk yard one , it probably needs to be reconfigured an programmed . Dealer only . In my thrity years as a automotive technician i have seen this , people changing parts without know what they were doing . Take it to a qualified repair shop .
Information for the speedo an odometer come over the CCD bus from the BCM ! I bet you have no idea what the CCD bus is ? You have no clue as to how this vehicle works .
