I have a 1998 Grand Caravan AWD with the 3.8L and have a problem that started with the engine just dying with no rhyme or reason!
I would drive it and the ignition would just cut out as if you turned the key off.
It would happen when driving or just sitting at an idle!
No codes where in the OBD and no check engine light would come on.
Usually would start right back up but then got to the point it would not start at all!
The auto shut down relay and fuel pump relay where going nuts clicking in and out even with the key off!
I traced all of the wires (DkGrn\Org) out of the ECM and found that from pin 6, which feeds the Auto Shut Down RELAY with power, along with the O2 sensors, Alt. Field Coil, and Fuel Injectors, was shorted to ground so I started cutting and found which wire that was shorted!
There are 6 wires junctioned out of Pin 6 but only 5 shown on the wiring diagram!
The 6th, which is showing a ground, is going into the firewall and I need to know what it is for before going any further!
Does it have something to do with the Alarm System going into the BCM or what?
Please help!!!
Thanks,
Dave
