Question about 2004 Dodge Durango

1 Answer

Can the PCM be at fault for a 2004 dodge durango not starting? I attempted to start my vehicle after it had been operating fine all day and it will not crank, the gauges and all dash lights flash, the horn relay is faint and buzzing as if it were triggering the antitheft mode. I replaced the starter and still the same (just clicking, not energizing the solenoid. The battery is fully charged but while attempting to crank the engine, the dome lights fade from very dim to not illuminating. All fuses both inside and in the engine compartment are fine. I checked voltage at the 30 amp fuse for the starter and I am getting currret to it as the ignition switch is turned. Some module is preventing the current to pass along the starting circuit. What say you? Do I need to get a new PCM or is this some other module that is malfunctioning in the theft deterent wiring diagram? Please help.

No , probably not . Do you know what a starter relay is ? It's located in the under hood fuse box ! That 30amp fuse sends B+ voltage an current to pin #30 , if you find an pull out the relay an look on the bottom you will see 4 sets of numbers 30 & 87 an 85 &86 . 30 is Battery voltage which when energized the relay will send this B+ voltage through pin 87 to the starter solenoid turning on the starter . You could take a jumper wire an jump those 2 pins an the starter should spin . Now , 85 & 86 are the control side of the relay ,Pin 86 should have B+ voltage supplied by fuse #32 10amp located in the junction block , maybe inside vehicle fuse box . Pin 85 is from the PCM , the PCM will supply a ground to this side of the control circuit if it see's a input from the park neutral safety switch . Do you know what that is ? Try shifting to neutral an see if it starts . Also if jumping pins 30 & 87 the starter doesn't spin . check the Positive battery cable using voltage drop . You may have a bad cable .

SOURCE: theft deterent

check if you have spark, if not look around the colum and see if the main ignition wires are tapped into by some aftermarket alarm, if so jump them back and try to start it, will this crank and not start or no crank at all? -jeff

SOURCE: turn key, dashboard lights like normal, nothing happens

get a boost... sounds like the battery is run down.... if you want to test that theory... have someone try and start the car while you check hte voltage on the battery.... it may well even need replacement

SOURCE: Starter relay clicks, engine does not start

Your problem may be a ignition switch.  This part is inside the steering column.  Your ignition key/tumbler turns this piece to start the vehicle.  I see a lot of these that go bad.  Some are easy and some aren't.  Your Chilton should tell you how to change them.

SOURCE: starter won't turn over, could

If the anti-theft light is flashing then it is in theft mode. If this is the case turn the key on and wait 1 hour then cycle the key to see if it starts if it does you have a anti-theft problem see dealer. sorry.

01 durango 5.9 no bus message but if I wiggle the black connector at the pcm the car starts but shuts down after a minute or so,meaning the fuel will not prime without me doing that ,prior to the no b


Remove the black connector to pcm . Check for corrosion pins . Then inspect the plug end for corrosion. I found moisture seep by the weather pack seal and wire on older vehicles.

Dodge Durango Won't Start, Turns over, NO BUS on instrument cluster


1998 - 1999 Dodge Durango 3.9L
2000 - 2001 Dodge Durango 4.7L
1998 - 2000 Dodge Durango 5.2L
1998 - 2001 Dodge Durango 5.9L

The PCM has 3 connectors plugged into it. Try wiggling each connector and listen for a clicking sound, starting with the connector furthest from the front of the Durango, and the middle connector with a white top.

If this doesn't help, replace your PCM. The PCM (power control module) can get hot, causing a short or broken circuit inside the module. Replacing the module will fix the problem. If your truck dies randomly when it's hot outside, but will start back up after it cools down, this is probably the problem.

Why does idle flucuate on 2004 Dodge Durango 4.7?


There appears to be an idle speed control problem perhaps caused by a sensor, throttle body issue, or vacuum leak around this area, in a rare occasion this could be an issue within the PCM. Although, there is no service light on there could still be stored codes on the PCM. It would be a good idea to have the computer scanned even anyway.

2004 trailblazer problems


Check for OBD2 codes, primarily a code indicating PCM memory is corrupt. My Trailblazer at times wouldn't turn over and start. Nothing at the key. When you attempt to start the vehicle and you turn the key to the start position, the PCM sends a signal to the starter relay to start the engine. Youtube video showed a mechanic warming the PCM with a hair dryer, and it would start. Tried it on mine and it started fine. If it is the PCM, the remedy is PCM replacement. Got mine from pcmforless.com about $100.00. They had to program the new PCM with the vehicle vin number. Once installed no more problems.

Possible PCM/ECM problem


Unfortunately that's not the case. Your battery was obviously strong enough to start the truck , and once started, the charging system increases system voltage to its operating range of 12.5v - 13.8v. Your battery may have only failed its AMP capacity and needed to be changed for that reason only. What is most common on your vehicle is when the battery goes dead or has been removed ,the ECM loses its learned memory and starts fresh again when the battery is hooked up again. Your start and stall, and / or stall in reverse is a result of the "minimum air rate adjustment" needing readjustment to compensate for age and wear. The dealer changed your battery but also did the "min. air rate" at the same time because if they didn't , you would still have your initial complaint of stalling in reverse.

Reset the ignition anti theft on my 2004 dodge stratus


If you are referring to the factory immobilizer, there is no resetting to be done.

The Sentry Key Immobilizer System (SKIS ) is designed to prevent unauthorized vehicle operation. The system consists of a Sentry Key Immobilizer Module (SKIM ), ignition key(S) equipped with a transponder chip and PCM. When the ignition switch is turned on, the SKIM interrogates the ignition key. If the ignition key is Valid or Invalid, the SKIM sends a PCI Bus message to the PCM indicating ignition key status. Upon receiving this message the PCM will terminate engine operation, or allow the engine to continue to operate.


For all faults except transponder faults and VTSS LED remains on steady. In the event of a transponder fault the LED flashes at a rate of 1 Hz (once per second). If a fault is present the LED will remain on or flashing for the complete ignition cycle. If a fault is stored in SKIM memory which prevents the system from operating properly, the PCM will allow the engine to start and run (for 2 seconds ) up to six times. After the sixth attempt, the PCM disables the starter relay until the fault is corrected.

I have a 2001 dodge durango and it dies while I'm driving but some days it starts up fine. Security light is on and blinking


The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

1998 dodge durango running fine when parked. next day, battery low would not jump start, changed battery, new battery cranks good but won't even attempt to start.


Go to AutoBeef.com and you will see there is a problem with th 98 & 99
Durangos. I took the advice to buy a refurbished PCM "Brain" from an online Florida company and my car has worked great ever since. Google for refurbished PCMs my cost <$300.00 and only 3 screws to change out. CAll the PCM company and tell they staff about your problem -- see if they think it is the brain. Sounds like same problem I had.
