ECM spark control

[mike 2112]

Looking for a thread that deals with anything that controls ignition spark.

That is very broad. What exactly are you looking for?

Well I have a no spark condition in my 1995 3.2l , and like a lot Of people here, I carry all major things I can to I don't get stuck Now I have the front Computer on the radiator support. Now I'm just wondering about the behind the glove box computer. All the obvious sensors I had in my trunk . But which computer is the right one . Thanks again, Mike

This is a 1995 3.2l ATX

The first thing to do is to check to see if you have any error codes which may tell you what component is bad. It won't be the main computer behind the glove box or the CCRM (Constant Control Relay Module for the fan and fuel pump) bolted to the radiator support. You will have 3 digit codes: http://wiki.wikisho.com/wiki/EEC_Self_Test_Procedure

Here is the ignition circuit for a '94:

Computer for 95 atx I think is D4U1

Ok, so from what I understand is that the crank sensor, dis module, coil pack and the main computer. All can be able to make a no spark condition. With the exception of the Cam sensor. Because it is a timing issue. Unless all the good sensors went bad sitting in my trunk. I just don't believe that . Any more advice on this situation . Thanks again, Michael

Have you tried checking the codes as I suggested? If you disconnected the battery that would have erased them, in which case on to Plan B....
