Vanagonauts:

I started my bus the other day to the sound of a crackling electrical short somewhere under the instrument panel, accompanied by a small wisp of smoke. After pulling the instrument panel, I can report the following symptoms:

(1) when instrument panel multi-pin connector below the tach is plugged in, the fuel pump runs and starter works, but engine just turns over without catching.

(2) with the multi-pin connector off, engine fires right up.

The connector and wires look fine (unburnt / no nicks / etc.). The instrument panel ribbon cables look fine. The switches are not causing the problem, neither is the speedo induction sender.

I'm lost re. the wiring diagram and why an instrument panel short would prevent starting. I see that a current track runs to the ignition switch, but wouldn't a short there cause the fuel pump not to run? This is on a 1990 GL.

Best, d.
