Tach is off

Hi..

Helping a friend with his camaro -88 and the tach and Oil pressure gauge is wierd.

Tach is staying at 2500 rpm when he shuts the car off and when he starts the tach is "oversensitive" it goes up to 6k when my scanner reads 2200 rpm, the oil pressure gauge is staying at 0 exept when the tach moves up then you could see the oil Pressure needle go up a little ........

any ideas?

/N.
