The first thing is to determine if the automatic shutdown (ASD) relay is turning on. Look for the wire that is the same color at every injector, the ignition coil, and the alternator. Measure the voltage on that wire at any of those places. A test light works best but a digital voltmeter will work if you watch it closely. You must see 12 volts there for one second after turning on the ignition switch, then it will go back to 0 volts. The fuel pump should also run for that one second.
Next, that voltage must come back during engine rotation, (cranking or running). That will tell us which way to go next.
Also check for diagnostic fault codes. Chrysler makes that easier than anyone else. Cycle the ignition switch three times from "off" to "run" within five seconds without cranking the engine. Wait for the Check Engine light to turn off, then count its flashes when it starts flashing. There will be from one to four flashes for the first digit, a pause, then one to nine flashes for the second digit. There will be a longer pause then the next two-digit code will flash. If you get code 12, that can be ignored. Code 55 will be the last one and is ignored.
