No spark. Checked coil wire to body, none. Checked power to fuse, good, fuse, good. replaced coil, still nothing. No power to coil (12 v) when key is on, but power is going thru the fuse. Does power to coil go thru computer 1'st, or constant when key is on? thinking brain it may be bad.
Replace the /the ignitor switch in the distributor electronic control switch its the ignitor in your distributor its the unit the wires going into ur distributor makes them complete ur spark

I had a similiar problem, found the solution there. It was the wiring harnes on the drivers side under the hood, just above the wheel well. there are a cluster of wires in a bundle. I unpacked the bundle carefuly and sure enough the were two or three wires all coroded, had wite powder from corosion. repaired the connections and bingo. I posted details at dodgeforums.com. browse around there. I posted pictures as well. this is a common problem.

did you change the main coil and coil wire?if so then check the ing resistor and then the computor box

First of all let's explain how the spark gets to the plugs. There is a crankshaft position sensor and a cam sensor. They are what determines when to fire the coils and injectors. The crank sensor is located on the passenger side on top of the bellhousing, the cam sensor is the pickup plate in the distributor. As the engin turns the send refernece pulses to the computer which grounds and ungrounds the ignition coil causing it to discharge and send voltager from the secondary coil wire to the center tower in the distributor cap. The rotor button recieves the voltage and distributes it to the 6 towers (1 for each cylinder) If you say you're getting spark from the rotor that tells me the primary side of the ignition system is working, and the secondary side is working into the distributor cap. I'd check for spark out of the plug wires at the plugs. Pull a wire and insert a #2 phillips screwdriver into it, hol the shaft of the screwdriver aprox 1/8"(no more) from the exaust manifold and observe the spark as someone turns over the engine. You should see a nice blue spark. If theres spark, spray a little gum cutter in the throttle body an crank it, if it fires you have a fuel problem. Install a fuel pressure gauge on the schrader valve on the fuel rail and observe it as you crank it. If theres no fuel pressure maks sure there's fuel in the tank, if so climb underneath and beat on the bottom of the tank with a rubber hammer, the pump may be going bad, sometimes you can jar them and make them run.

then i would replace whats called the hall effect sensor its that black plastic plate you see when you take dist cap off. just pull rotor and lift up the sensor.dist cap is what holds it on.also under the sensor will be a stamped sheet metal piece that looks like the top of a castle wall. make sure its not loose on the shaft.if it is then new dist will be needed

Here is a firing order diagram and note the distributor cap latch positions between terminals 1 and 2 and 5 and 4, and let me know if you need any help to understand this diagram or if you require any further assistance.
