The car is a 2003 sorento 3.5 v6 with only 34,000 miles, the car is only used once in a while, and is in spain, the last time I used the car I topped up with fuel and went to do my journey.A mile or so into journey the car started miss firing badly and backfiring a few times no power ect, until finaly it died, it did restart but would only tickover and then died, it would not then restart. Towed car home, only fault codes on code reader where p0303 no 3 missfire and p0102 mass air fow. I have fitted new plugs, new mafs and also crank position sensor, all timing marks where spot on, I have checked fuel pressure, compression ect.I have also checked fuel quality ect, as I had only just put fuel into car. Now when I try to start engine it appears to be flooding, I say that because I have a fuel pump cutout switch fitted, and after trying to start with fuel pump on as normall it may fire a few times, but not run, if I then switch fuel pump off, it will after a few turns fire up momentary as though its burning the fuel left in the cylinders, there are no fault codes showing.
any help please
have the same problem?
