From: Western NY,
you said you had power at the injectors?do you have a ground pulse when you turn the engine over? if you don't have a noid light 'injector light' a simple way to check if the injector is firing is take a 194 bulb,marker light bulb bend the wires out. unplug a injector,push the two wires from the bulb into the plug and turn the engine over. see if the bulb flashes. a led test light works good for testing injectors and with a led test light you can see if you have a ground pulse at the coil. could save you time running to the junk yard.

Coil and injectors both get power from the ASD relay.

last post said he had lost spark.checking the injector pulse at all cyls then checking for a ground pulse at the coil would eliminate a bad pcm and lean toward a bad coil. if only a few cyl. firing could be a bad quad driver in the pcm.more than once i had seen a bad dist cap that only a month old cause a no start, rough running condition. a bad rotor with high resistance can cause a lot of troubles as well. i would try a coil myself they seem to be the weak link and replaced a few of them.

^I think that is sound advice.
I'd opt for a quick simple looksee, just in case, if not done already:
Pull all the wires, pull the cap, then re-install according to the following posts:
Fire order with respect to the cap

I'm recommending this as it can be difficult to get it right on the cap in addition to seating the plug ends due to access behind the Keg. Especially if you have sausage fingers....

I think so. But you need 2 people. I used a multimeter. I found out that the noid light sets at the parts stores did not have a Chrysler one OR the dudes just don't know what will work for our injectors.

a regular test light will work just hook the test light to the positive side of battery. i use a small cotter pin straighten out and push into the terminal.if your by yourself you can attach the clip side to the pin and the tip of the test light to the battery.using a cotter pin wont ruin the plug as well
