Dodge Durango Problem
Engine Affected: 5.9L V8
Average Mileage: 140,000 mi (130,000 mi - 150,000 mi)
Stepped on the gas, heard a pop sound, lost all power but engine idled rough. Was able to coast it to my house where it now sits. I was able to get it to turn over once since and it idled very roughly. Since then it's only been a crank and no start. Every now and then I smell a bit of gas, but I imagine it is only from the injectors trying to start. I did hook up a OBD II Scanner to it, the codes were P0300, P0302, and P0308. I know these are misfire codes, and I did clear them out. It did not solve the problem. It still cranks but does not start. And no more codes are showing, and the scanner says PASS as well as the dashboard option for checking the errors. It says P done when tested. I replaced the Crankshaft sensor, reset the PCM, and still nothing. Help!
Constant P0308 code.
