I started a 1941 Plymouth coupe on to 2001 4x4 Dakota frame 3.9 engine three year ago got back at it .Of coarse forgot alot and maybe missing parts.So at this point I am trying to get engine running .engine starts but runs rough and dies.Do all BCMs have 3 wires plugged into them? instrument cluster shows nothing when running or with key in on position .Thanks Fearski I Need Help

 

The BCM or CTM has 3 connectors.

The instrument cluster, what year is that? Dodge changed the computer bus in '01 to PCI (one wire) from the '00 and earlier CCD version (2 wire). They are not compatible.

On the rough running engine? Did you move the distributor at all? If so, the fuel sync may be off.

 

The Dakota is a 2001 I am talking about BCM by driversode left kick panel have tried moving distributor changed cap and rotor I only have 2 wire going to BCM from pics shows three fuel pressure 60lb thanks

 

There are two versions of the CTM or BCM. Both have 3 connectors. Can you post a pic? If everything is from an '01 Dakota it should work. Check for power to the instrument cluster.

Moving the distributor changes the fuel sync. The injector timing is likely off. You'll need a scan tool to set it correctly.

 

Will try atach pic where does power for cluster come from? What wire am I missing in BCM? Thanks

 

It's hard to tell some of the colors but it looks like you have two of the three connectors. Connector 2, the middle, is door locks and some lights, probably not an issue.
Connector 1, the gray one, pin 10 violet with a yellow tracer is for the PCI bus.
Your cluster needs that same connection, on the black connector, pin 9, again it is violet with a yellow tracer.

Power for cluster is also on connector 1.
Pin 1, dark green with a gray tracer, 5v+ transmission range sensor.
Pin 2, dark blue with a white tracer is 12v+ (run).
Pin 3, black with orange tracer, door disarm
Pin 4, black with light green tracer is a ground.
Pin 5, black, is a ground
Pin 6, pink, is constant 12v+
Pin 7, red with white tracer, is 12v+ (run and start).
Pin 9, violet with yellow, pci bus
Pins 8 and 10 no connection.

 

Ok great thanks I no not haver locks and such so possible that not wires to go there on BCM. I have 12v to pink wire constant and key on to blue white pin 2 still no gauge cluster action other than high beam lite on for no reason. What kind of scan tool would I need to reset injectors don't want break the bank.thanks fearski

 

On the cluster, On connector 2 (gray connector) Pin 9, red with gray tracer is the high beam driver. Might have a short there.

The previous post, those are on the black connector.

DRB III is the old school dealer tool. There are newer generic tools. Hopefully someone else can chime in.

 

Dan got you started.

Since it is running, you're probably within shooting distance of cam sync - possibly the MAP or TPS are upset in addition. IAC might also be back in learn mode. Make sure the 90* MAP hose is intact under the sensor going into the throttle body.

Up in Wisconsin...I don't know any Dakota guys offhand with a DRB. I think there might be a couple Flyin Ryan Performance customers/vendors up there with a Snap-On MODUS. I think the second generation of those supports our trucks.

Verify that pin 7 (red/white) has power in run position. IIRC that comes directly off the ignition switch on the column.
