It should be on the drivers side underdash. here is a large group of wires under the hood that bolts up to it. Culprit could be an ignition pickup or PCM. Do you have spark and does it stay sparking or does it start to spark and then stop?

Try replacing the ignition module. It is located in the distributor. This is what gives the PCM the reference to turn on the fuel pump, fire spark, etc.

I have PCM question for a 1997 Doge Neon.?
How would I know if The PCM is not working, fuel pump and the ignition is not starting and theres no spark to the spark plug or to the distributor it has no spark to the spark plug or to the distributor it has no juice when you try to start the car. Fuse box is working on both ends. I checked the coil and its working. My car is a 1997 Doge Neon. Start by having it checked for trouble codes. If the PCM is not working; the easiest way to check for a PCM problem is by turning the ignition (the key) from position I to II, do not start the engine. The CEL (check engine light, yellow in colour) should light for 3 seconds and then turn off. If it does not turn on, then the PCM is not working correctly or there is no power going to the PCM. Then I would start by checking the PCM fuse and checking if there is power going to the PCM. Earlier model neons have PCM problems. Only a retarded manufacture puts the PCM under the hood exposed to the extremes of the elements. Honda is better, put it inside the car were is belongs!

Please help. There is possibility that I bought a faulty PCM with the same problem that I had from the original, but I dunno.

Will the ecm pcm from a 2005 wrangler x work on a 1997 wrangler sport?
if it's the same drive train i don't see why not. ie; same size engine and same transmission. Most likely no, they are too far apart in years.
