Have you done any work with the ignition or ECM lately? Have you checked your battery terminal that they are clean and have GREAT contact? I ran into that actually at NEFR and found out that the culprit was the link in the middle of my disconnect assembly.

![]() By the way, do you know of any interlinks which prevent turning on the ignition? Everything else works except the ON and START positions of the key switch. The ACC position works normally. |

Ok. I'll check the grounds.
At this point I'm trying everything.

Checked the grounds and they're all intact. Does anyone else have any ideas?

Check the 60A fusible link on the positive battery terminal.

Took everything apart at the positive terminal and both the main and the alternator fusible links are good. And there is power at both the alternator and the starter.
You know, it is behaving like there is something disabling the ON and START circuits from operating. And although the OBD computer powers up fine, it is not able to communicate with the ECU, so there seems to be no power going to the ECU. Might you know if there any sort of "fail safe" disable mechanism that may have gotten triggered? I saw in the Owner's Manual there is an anti theft ignition disable security device, although my model supposedly doesn't have it because there is an empty spot where the LED indicator would be at the leading edge of the dash near the passenger side of the windshield. I'll try any other suggestions you can think of... |
