I recently bought my wife a 2000 Durango 5.9L 360. Just 300 miles after the warrany the water pump went out. I replaced that with no problems. The first time I started it up the check engine light came on. It put out that both o2 sensors were bad. I replaced those with no problems. I cleared the codes and almost immediately the light came back on saying both o2 sensors were bad. I was told by the dealership that some of the Bosch o2 sensors didn't always work with chrystler. (Whatever) So I replaced them with Mopar sensors. And again the light came back on saying o2 sensors high voltage. I cleared the codes again and of course it came back on. This time saying both o2 sensors AND torque converter circuit high voltage. The next day or so it tried to take off on it's own as I was sitting at a redlight. A few days later the light came back on saying o2 sensors high voltage AND crankshaft position censor circuit malfunction. I unplugged the battery for a short while and all was well for a few days. Then as I came to a stop the ABS light and AIRBAG light came on, all the gauges stopped working and then the check engine light came back on. It would all go back to normal as soon as I started accelerating then come right back as soon as I started to brake.
The next day it wouldn't even start. The odometer flashes and then reads no bus and it would just crank. After being stranded several hours and paying for a tow truck to get it home I tried to start it again and it fired right up. I drove it around for a few minutes and still the gauges would stop working and the lights would come on everytime I stopped. I had it towed to the Dodge dealership and after 2 1/2 weeks they still can't tell me what's wrong with it. They said I need a new gauge cluster. ($1,020) But that wouldn't cause it to not start. So I found a PCM at a salvage yard, swapped them out and nothing changed. It started but then immediately died 3 times and then just wouldn't start at all. I hooked the code reader up to it and it says there are no codes even though the ABS, airbag, security, brake, gas, AND check engine light are all on. I checked all grounds I could find. So my question is, what should I do now? I don't have money to start buying parts to find out it wasn't the problem. At at wits end here.
