I have a 2002 Dodge Grand Caravan on about 8/11 the check engine light cam on and smoke and raw fuel were coming out of the exaust. I immediatly shut down and began to diagnose the problem. I found the wiring harness on the injector feul rail to be faulty. The harness is route around the ignition coil directly over the exaust pipe. The insultation had broke down over time from heat and bare wires wer touching each other. The result is a potential fire hazzard. The end result was also a ruined pcm. The injector wiring harness has no additional heat sheilding on it, but where it plugs into the main wiring harness the main wiring harness has heat sheilding material.
