Sounds like low battery power (no doubt a latent by product of the loose terminal); I suggest charge it up and your idle/die thingy will stop. Also, this TSB could be interesting to apply...

Customer Concern: The engine cranks but will not start. NO BUS is displayed on the odometer display.

Tests/Procedures: 1. Unplug all the sensors that have 5 volts going to them. These include the Manifold Absolute Pressure (MAP) sensor, Throttle Position Sensor (TPS), Crankshaft Position (CKP) sensor, Camshaft Position (CMP) sensor, Governor Pressure Sensor (GPS).

2. Cycle the key to the "off" position for 10 seconds to allow the Powertrain Control Module (PCM) to reset. Turn the key back on and check to see if the NO BUS message is gone and check to see if there is now 5 volts reference voltage to the sensors at this time. If so, then start plugging the sensors in one at a time until the voltage drops. Once this happens, the sensor that was just plugged in is shorted, replace it.

Potential Causes:
PCM
MAP
TPS
CKP
CMP
GPS

Confirmed Fix: PCM
Diagnostic Codes: None

Category: Engine Performance Starting
Call Date: 10/21/2005
Key Number: 114746
What Fixed It / Confirmed Fix: Governor Pressure Sensor
The gov. Pressure sensor was shorted in the new trans.

Customer Concern: Gauges are inoperative and the odometer displays no bus. Cranks no start. No spark, no injector pulse and no scan tool communication.

Tests/Procedures:
1. Unplug the Throttle Position Sensor (TPS) and check the voltage on all three wires. Two wires should be 5 volts and one is the sensor ground.
2. If there is more than 5 volts on the two wires, check for a bad ground for the Powertrain Control Module (PCM).

Potential Causes: Confirmed Fix / Bad PCM ground

Finally, for this vehicle:
1998 - 1999 Dodge Durango 3.9L
2000 - 2001 Dodge Durango 4.7L
1998 - 2000 Dodge Durango 5.2L
1998 - 2001 Dodge Durango 5.9L

Symptom: Engine will not start. Gauges are inoperative. No BUS message displayed on odometer.

System: Body/Chassis Electrical, Emissions/PCM/Fuel, Engine Electrical

Codes: N/A

Problem 1 of 2:
The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Crankshaft Position (CKP) Sensor.

Test and Fix:
- If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be dead. The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) sensor.
- If 5v is not present, unplug the Crankshaft Position (CKP) Sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit.
- If the voltage is now 5v, replace the CKP sensor.

Problem 2 of 2:
The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Camshaft Position (CMP) Sensor.

Test and Fix:
- If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be dead. The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor.
- If 5v is not present, unplug the Camshaft Position (CMP) Sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit.
- If the voltage is now 5v, replace the CMP sensor.

Hope this helps.

2004 Dodge Durango 4.7 liter started then just stopped will crank could be fuel line freeze up.Also told could be Cam shaft senor Crank shaft sensor had check engine light on did OBD said EVAP Leak


Suggest before you start to replace parts See what is missing , fuel or spark . Evap leak has nothing to do with it . Videos on youtube testing spark and fuel pressure . special tools needed . You probably would be better off just taking it to a qualified repair shop that has all the tools . Probably know in less then an hour what's wrong .

2001 Durango. Why won't it start?


I would closely check the wiring to make sure that the connector for the senor has not dislodged, it happens. Also if you have an OBD reader, the computer would tell you what is wrong.
