    . Check all underdash and underhood fuses with a test light or multimeter.

    . Check coil.

    I checked all the fuses in the car.
    I even change most of the relays.
    That was the first step I took before I started changing anything else..
    Please help...

    When was the last time you changed the timing belt? Have you checked to make sure it hasn't broken or skipped a few teeth?

    . Clean main ECM ground.

    . Check coil wiring and coil interface module.

    . Check for ECM failure. The ICM-function is resident in the ECM.

    Did you replace the coil pack? On this generation vehicle, ECM, Crankshaft Position Sensor, and coils are the normal culprits of "crank but won't start" situations.

    Yes, I got a new one at the autopar store.
    Along with the crank position sensor.

    If all components are new, do you have power to the coil? If not, the ignition switch may be bad. Check for wear, pitting, or melting.
