2002 Silverado

The oil pressure guage won't go to zero when you shut it off. And even the slightest backfeed of power like when you turn on the lights can cause the needle to move.

Doesn't go to zero when I turn it off, but the backfeed doesn't seem to effect it. It will go to zero when I turn the key on but don't start it, when I turn it off it jumps right back up.

I have a 2002 Silverado with the 4.8 mine reads 0 when off and goes up when started, depending on speed and what gear I am in it will go up and down all the time. Never staying still.

I've got the 5.3 and up until yesterday my gauge did like yours, up and down when driving and zero when off. I guess I'll take it in on Monday, find out what the problem is.
