Measure the voltage on the feed wire to the coil pack, any injector, or either small wire on the back of the alternator. That used to be a dark green / orange wire but the colors might have changed for a 2003 model. You should see battery voltage for one second after turning on the ignition switch. What's important is whether that voltage comes back during cranking.
