I have been trying to fix my car for over a month now and still can't figure out what is wrong with it. I have replaced the coil pack, ECU, and CAM shaft sensor so far and still nothing. The car turns over but will not start. There is no spark. I can't figure out what is wrong with it. Please help!!

Check the fuel pump fuse and the auto shut down relay. They are both in the fuse block just behind the battery in the engine compartment. I'd suggest taking the auto shut down relay and putting it in place of the starter relay. That way if the starter doesn't engage, you'll know for sure that it was the auto shut down relay and you can replace it to see if that solves the problem.

Auto Shut Down relay activates when it does not see a crank shaft position sensor signal. It is located under the alternator. Camshaft sensor has nothing to do with it. You can unplug the camshaft sensor and it will still run if the crank sensor is good. Check fuses, swap relays just as a check, then change the crank sensor. More than likely that is it. Did have one where the transmission speed sensor on the differential shorted out internally and was killing the crank signal. Unplugged the speed sensor, started right up. Worth a check, this was on a '99.

If you used a head from a newer model, that may be your problem.

Is there any way to get the 03 head to work on a 02?
