2000 Dodge Avenger Spark Resistance On Plug Wires Check Coil

First check if the automatic shutdown relay is even turning on. Measure the voltage on the wire that's the same color at the coil pack and every injector. That's usually a dark green / orange wire. You will see 12 volts for one second after turning on the ignition switch. What's important is whether that voltage comes back during engine cranking.
