    exactly the same problem. But I have found out that my PCM2 fuse was shot down. So I replace it and the car start. Now after 5 seconds it is shutting down. I think it is fuel problem...... I'm going to investigate.

Start by checking the battery. if you have a volt meter. you need atleast 13.6 volts to crank that car. if less than that, try recharging the battery.
you can take your battery to autozone and they will preform a load test on your battery to see if you need to replace it or not. also, is there a security system? Is there no power (do the lights come on when you open the car doors?) , or it just wont turn over?
