Car starts and runs for thirty seconds and shuts off! I have replaced the spark plugs, ignition wires fuel pressure regulator, fuel pump, fuel filter, cam sensor, crank sensor and still have this same problem?

If this has a security system that may be the problem. If no owner's manual look online for how to reset it for your car. It kind of sounds like it is. If that does not work have a mechanic scan for codes.

You do have a security system on your car so try what I said in first reply about a reset then it will need scanning for codes if it doesn't start.

OK Will Do! One More Thing? I Jumped The Fuel Pump To Alleviate The Relays And It Still Does The Same Thing? What Would Stop The Fuel From Getting To The Throttle Body? Also If Said Security System Is Faulty why Would It Start at All? Thanks Tom.

It's not an alarm you probably have a transponder or a chip in your key to match the system our manual says you do have it and being a kind of premium car it would have it. It doesn't send an alarm anyhow it just won't allow the car to start and or run longer than 30 seconds.
