I have a 1994 3.3 ES which is a non starter no spark.. no power coming from the ecu this is the one located below the battery tray so need to replace it, BUT the part number which is on the label cannot be found on any search.
the part number I have is 468 6539, can anyone help run out of ideas to track one down.

 

are they interchangable

 

The other problem I have uncovered while trying to track the part number down for the ECU/PCM is that the VIN number is coming up with no matches !! I have triple checked the vin numbers on the motor and they match. Any thoughts been off the road 6 weeks now trying to sort the problem out as there are no mechanics on the island where I live that know what's what so having to do DIY.

 

Have you had a look at this file?

There are quite a few things it's worth checking before replacing an ECU. My copy of Chrysler PAIS has decided to stop working, if I can get it running I'll find the ecu part number

Hi Richard
Appreciate that thanks lots of useful info there, but still got this issue of the part numbers so if you do find any ref to my part number that would be brilliant, spent 4 hours searching again to-day still no joy.

Thanks

 

Hi Richard
The one thing that is giving concern is the malfunction indicator lamp I am getting no flashes at all using the ignition key on off routine, does this on its own point to the PCM?
