I started my car this morning (cold start) and about 3 seconds of running the car the gauge went from the normal every day dummy light status to 0... I shut the car off immediately and after a few seconds re cranked it. The exact same thing happened... It worked fine for about 3 seconds then bottomed out to 0 in a hurry like it was unplugged) Does this sound like the sender is going bad, or am i just losing my oil pressure? (im hooking up a pod gauge to it when i get home, but wondering if these symptoms sound familiar to anyone.)
