Ok so yesterday we got our first snow fall and of course I was out dickin around in it. All of a sudden my tach and speedo just went out, my check engine light came on and my odometer said "nO bUS". Does anybody no what that code means? This has happened to me a couple times before and usually goes away after about a half hour or when I restart my engine. I have brought it in to the shop in the past and had them hook the computer up and everything checked out ok its really baffling me and little shit like that pisses me off so if anybody can help me out i would be greatly appreciated.

No Bus means that there is no circuit between the instrument cluster and the ECU. Sounds like a bad ground to me. Different gauges on the cluster ground through different circuits so the symptoms you are seeing make sense.

You'll need to pull the cluster out of the dash. There are two ground circuits on the gauge cluster. When you look at the circuit board, the GND circuit is for the cluster lights temp, oil pressure, and voltmeter. The LGD circuit on the board is for the tach, speedo, gas gauge and low fuel light. Hook a new ground into the LGD circuit and that should solve your problem.
