[Shop-talk] Oil-pressure gauge goes nuts on Suburban.

[pethier at comcast.net]

2004 Chevrolet Suburban.  Picked up my truck after it had been sitting out in the 11-degree-F cold for a while.  Started OK.  The oil-pressure gauge was pegged WAY past the end.  Stopped the truck after it was warm and went into a store.  Came out and turned on the ignition.  Needle went to full scale.  Started the engine and needle went to full-on pegged again.  Stayed that way until I shut it off in the garage.  Needle went to zero.  Ignition on, back to full scale.  Restart engine, back to superpeg again.

All the other gauges seem to be acting normally.

Anybody else ever seen anything like this?
