Need a pinout for my 2002 durango 4.7 2wd (3 plug ecm) & pcm? Is the pcm (1 plug) the module by the headlight & the ecm (3 plug) I changed checked & double checked all sensors, 5v ref signal goes in & out of crank, cam, tps, map. Fuel & asd relays pass the test. I jumped the fuel pump relay & the pump works. No codes except inst. Reset codes 920,921,999. This morning cold outside 20deg cooler than yesterday in sunny florida in the 40s this morn Wow, in south florida. The no bus cleared & instrument codes gone & the motor starts runs for5 mins & shuts off. No codes doggonit. Wriggled eveything started again 2-3 mins died again. I down to the wiring. I have a very nice fluke multimeter wanna check circuits from ecm pcm & connections between the ecm pcm.
