The start engine light is on and doenst turn off. It seems like the car is in anti theft mode. i reset the battery and the engine starter light went red for few minutes and then turned green again.
Hi there:
You will have to pinpoint what the engine is missing...
- Spark
- Fuel
- Compression
All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.
Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.

With the doors shut, insert the key into the drivers door lock. Lock and unlock the door 5 times. This should reset the system. If that doesn't work you should contact a qualified repair shop.

You may have corrosion inside your battery cables or a loose connection somewhere.
If you have a voltmeter connect one lead to the POSITIVE post of the battery and the other to the POSITIVE post on your starter while you have a friend crank the engine
WATCH YOUR HANDS!
This is called a voltage drop test and you should see less than 0.5v on the multimeter while you are trying to start it, if you have high resistance (corrosion bad connections) you will see a higher voltage. 0.5v is the MAX you should see.
Do the same test on the ground side of the circuit, connect to the NEGATIVE battery terminal and the starter case, your voltage reading should be 0.1v or less

Okay you may want to check to see if the sensor on door lock cylinder hasn't fallen off from the lock itself. Pull of the door panels and check the wires at the door lock cylinder. Hope this helps.
