2004 kia sedona, started off would not turn over, scanned codes and stated crankshaft sensor, tore whole left side apart near timing belt to changesensor and was not even issue. Changed the starter now starts but runs really rough and smoking and smells like raw gas, have changed crankshaft sensor, starter, plugs, and injector

If you have been cranking it a long time, unburned fuel has accumulated in the cylinders and even into the crankcase, drain oil and change oil and filter, then pull the vacuum line off the fuel pressure regulator, if ANY gas is in it, replace the regulator. DO NOT run it until you do the oil and filter!
