1996 Chrysler Town and Country CHECK ENGINE LIGHT, MISSING

Replacing the plugs should have helped if anything. The check engine light coming on indicates there is a trouble code stored in the computer. The code will indicate where the problem is coming from. As far as the no start now, is there any chance you mixed up the wires when replacing them? Also, I need you to check for spark and fuel to the engine. Here are the how to for checking them.

Check for both and let me know if what you find. If it won't start, chances are one will be missing.

Let me know what you find, and thanks for using 2carpros.com.

The wires were placed in properly , however I did switch one plug from top 2 bottom on same plug & tried to start & that is when van would not start(crank but would not turn over), I then placed them back where they belong & Van would still not start but would crank. Could switching the wires cause a problem with another part or with plugs themselves?
I did check... & fuel is going to engine, but no spark, I then today replaced distributor & still does not turn over. I replaced speed sensor a month ago, which it now sounds the same ( cranking but not turning over) I am considering replacing that again if that works it still does not address original problem which was check engine light & running like it is missing a cyclinder. What else could it be?

One plug wire wouldn't have caused this, so you didn't cause any damage to it. If there is no spark, my next concern would be the crank sensor. Have you checked that?

We changed the crank sensor no change. Unsure what this problem could be. We replaced transmission 2 months ago also.

Replace ECU from a 1998 Dodge caravan & now it is running good but am getting code 11 from computer. Checked possible problems online but do not know how to reset logic module. Do you have any ideas??

Basically, this means power was removed from the logic module (disconnected or dead battery, etc.) and the logic module has no memory of seeing a signal from the ignition reference sensor. Crank the engine and check for the code again. If the logic module saw a signal, the code will be cleared. This code will not show up if the sensor simply fails. The logic module must be reset and the engine cranked to see if the sensor is working. To do that, you need a scanner. Most parts stores will do it for free.

LEt me know.

I received the posting back, but no reply. Did you have another question?

Joe

It is still running check engine light did go off after a couple of drives but is now back on?? I am not going to worry for now. It may be on because ecm was from a 3.3 instead of 3.8 engine.
If you do not think that will cause a problem, I am fine. Thanks for your help :)

That could cause the problem. Is everything else working properly? We were always when changing the ECM, it had to be one with the exact part number. Was it different?

It sounds like it is running the same as before, only problem in the first few runs it stalled while in reverse. It has not stalled since. Do you think it could cause damage running on this ecm?

If it is running good, it shouldn't cause any problems.
