hi, the problem you are having sounds like an imobilser problem does your key have a fob that unlocks the doors etc check this is working if it is then the problem could be with the key itself as they are programmed so that if somebody used a different key in the ignition it wouldnt allow the car to start.
The only way of knowing for sure is by taking it to a main dealer because the imobilser problems wont show up on a diagnostics machine the main dealer will be able to test the key or fob for you they should test it for free but if it needs replacing then you will have to pay for this unless its a common fault if it is common problem with that make and model they will replace this for free.

im sorry their is no easy fix for this problem but it is more than likely your imobiliser if it was say something like starter motor your car wouldnt have cut off whilst running so it points to an imobiliser problem so get this checked.

Let me know how you get on or if you require further assistance ok

What you need to do is check you fuel pressure. Go to a local auto parts store and buy a fuel injection pressure tester. The pressure fitting is on the top of the motor its a 3/8 ish sized metal line and has a screw on fitting like a tire valve does. This line comes up from the back of the motor to the right of the distributor and goes down into the intake. Make sure to have a rag handy to catch the fuel seepage. After you connect the pressure tester turn the key on and off three times and read the gage you should have atleast 58 pounds of pressure. If you have 56 pounds it won't run because the fuel injectors are a poppit valve style and need atleast 58 pounds of pressure to operate.

WHEN YOU REPLACED THE FP DID YOU OR THE DEALIERSHIP REPLACE THE FUEL FILTER MAYBE YOUR PROBLEM ....

Testimonial: "They did replace the filter but thank you very much for the tip."

sounds like the starter motor is jammed or shorting get someone to turn the ignition to start and at same time hit starter motor, if this does not work, put vehicle in gear and rock back and forth, this hopefully will release a stuck starter, if it is auto you obviusly cant do that, you can try attatching wires directly from your battery to the starter motor ie live to the red connector earth anywhere on the starter(not on the live terminal) and see how that works...hope that helps

If you know the batter is good.

Check the Starter to see it is getting power.

Get a test light [6.00] and see if the starter will light up the test light.
If not - then you may need a new starter. From the sounds of it you might want to take it to a professional as this can be a very labor intense job because the starter has to come out the bottom.
