Do you have a volt meter to do some tests?
Customer: replied 8 years ago.

I have a multimeter same thing right?

Expert:  Mopar Certified replied 8 years ago.

Good Ok, here is a pic of the 6 way distributor connector and the pinouts for the connector.

I need you to check for 8 volts, with the key on, at pin #2.

 

I also need you to check pin #6 for 1.5 to 2.5 volts while cranking the engine over.

 

Let me know what you get.

O.K. I've got 9.1 volts at pin #2 and nothing on pin 6
Expert:  Mopar Certified replied 8 years ago.

Ok, so with no voltage reading on pin 6 it means the PCM is not triggering the coil. We have to go to the crank sensor to see if it is working.

Ok, test for the 8 or 9 volts on pin 1, with the sensor disconnected, and 5 volts on pin 3.

Then stick a pin or paper clip into the backside of the connector for pin3. Check your voltage again to be sure you have made proper contact. Now plug the connector back in.

 

Rotate the crankshaft pulley by hand while watching the 5 volt. It should switch from 5 volts to zero and then back to 5 volts and then zero again while you are rotating the pulley.

 

Let me know how you make out.

Customer: replied 8 years ago.
crank sensor goes from 0 to 5
Expert:  Mopar Certified replied 8 years ago.

Ok, then you would have to test this wire directly at the PCM. If the PCM is seeing a crank signal but not triggering the coil then the PCM is at fault.

 

Be sure and verify there are no broken or corroded wires between the crank sensor and PCM and the PCM and distributor.

I think we're on the right track where exactly is the pcm located on this car . I see two possible next to the battery but the plugs are different?
Customer: replied 8 years ago.
sorry not next to the battery , I meant next to the power dist. box thanks
Expert:  Mopar Certified replied 8 years ago.
Yes, they show it right next to the pdc. It hasXXXXXconnectors.
Customer: replied 8 years ago.

Got it Thanks, XXXXX XXXXX 32 I only get .01 to a .27 max and nothing on 4. I'm going to check the wire now. Anything else I should do?

Customer: replied 8 years ago.
Correction I am getting 4.99 to the pcm that must be the problem, does it send a signal out that I can check for or is that what I'm checking?
Expert:  Mopar Certified replied 8 years ago.

When you did the test at the crank sensor and saw the voltage go from 5 volts to zero and back again, this shows the crank sensor is switching. You are looking for the same thing at the pcm.......this just ensures the pcm is seeing this signal and that the wire isn't broken somewhere between the crank sensor and the pcm. You should be testing it the same way with a pin or paperclip pushed into the backside of the connector......this is with the connector plugged in.

 

The signal out is pin 4. This is the same wire you checked at the distruibutor and we were looking for 1.5 to 2.5 volts.

 

If the PCM is seeing the 5 volts go to zero and back to 5 volts as you rotate the engine then it is getting the crank signal. If it gets the crank signal is should be sending out the 1.5 to 2.5 volts to trigger the coil.
