Is this after a rebuild or for whatever reason after removing the front cover? If so you might have missed the o-ring that seals the oil path from the pump to everything in the motor that needs oil.

If that is indeed your problem, read that page very carefully. I screwed it up the first time and had to do it all over again. That was a very long day.

Might also just be the wire from the gauge to the oil sending unit under the oil filter. Mine was disconnected when i changed the oil cooler lines and i didnt notice till after i starte dthe car and had a similar incident.

to add on to everyone else here...
if the gauge is sitting at -10~ then the gauge itself is probably toast (like mine). If it never goes below 0 then it's something someone else has mentioned above.

grounded the wire off oil pressure sender, gauge peged out, so bad sender or i really have no oil pressue
So if no oil pressure could it be a oil pump ? ( oil dip stick checks good) only 110k on motor, can you change a oil pump without removing motor? goona pull sender out tomorrow see if oil shoots out hole

Anyway, OP, if you hear a buzzer there should be an indicator light illuminated on top of the dash telling you which issue it's whining about, unless it's from revving too high, I don't think there's a light for that that comes on the same time as the buzzer.

another cheap and dirty (and slightly messy) way to check for at least some oil pressure is to pull the INJ fuse (so your car doesn't try to start), loosen up your oil filter a bit, and have someone crank the engine while you watch for oil seeping from the filter. If you get seeping oil, then you know you're getting some sort of oil pressure in the system. Certainly isn't the best way to check, but is a way none the less.

there is a buzzer for redline with no light indication, there is a buzzer for coolant level at the radiator top with a light association and there is a buzzer for oil level with a light association. the clock/idiot cluster commonly fails also, or the bulbs simply burn out(less common than cold solder joints in the idiot cluster though).

Some time in the future gonna have to retap holes for the cap that holds shifter **** to top of tranny, not sure how they messed that up, looks like tranny is made of alumminum there, or is whole tranny alluminum
