internal88 :

Do you know how to retrieve the code from the ECU?

Here is the PROCEDURE
The provisions for communicating with the Engine Control Module (ECM) are the Data Link Connector (DLC) and the diagnostic request terminal in the duty check DLC.

The duty check DLC is located in the right rear engine compartment near the battery. Diagnostic Trouble Codes (DTCs) stored in ECM memory can be read by counting the flashes of the malfunction indicator lamp (MIL) after grounding the diagnostic request terminal in the duty check DLC. When this terminal is grounded, the ECM enters its diagnostic mode and outputs DTCs to the Malfunction Indicator Lamp (MIL) .

To ground the diagnostic request terminal in the duty check DLC, connect a paper clip between duty check DLC cavities "2" and "3". At this point, the MIL should flash continuously . This would be the following flash sequence: "flash, pause, flash-flash, long pause, flash, pause, flash-flash, long pause, flash, pause, flash-flash," etc.
If more than one DTC is stored in the ECM's memory, the DTCs will be repeatedly output from the lowest to the highest, with each DTC being displayed three times.

Once you get the code please let me know. I will define it for you.
