Fixed with Fuel rail pressure sensor.***UPDATE!!***
FIXED WITH A FUEL RAIL PRESSURE SENSOR.
Stock v6 no upgrades. I have changed the fuel pump and filter, replaced the cam positioning sensor, O2 sensors, exhaust system, plugs and wires, coil pack, battery and tested the alternator.
We are good. Had the oilchanged and was good.Aw your car is a 04. A friend had problems with his fps once. The diaphragm within the sensor busted and pumped fuel into the intake manifold. Car wouldnt start and was heavy on the gas smell. We pull of the vacuum line and gas came out. The manifold had a quart of fuel in it, the oil pan was full of gas....it was a mess.
