I got in the car this morning and I noticed the "check Gauges" lite was on...
and I looked and noticed that my oil pressure gauge was not working at all.

What should I checck first?

where is it located on the car?

thanks

its a 97 V6 3800 car if you needed to know

 

on the firebird 97 V6 3.8 the oil pressure sender is located below the serpentine belt.. just to the driver side of the oil filter.. little black circular thing with a wire harness attached to the end, kind of looked like an O2 sensor.
I repalced mine a while back and it was about $20 soemthing at the parts house. just out of curiosity what OBD code did it throw as it is could be a circuit??

 

Are you positive you are getting oil pressure?

 

I have the same problem on my truck, first time I saw it I freaked out a little bit and tossed a mechanical gauge on there to confirm pressure.
Of course the first time it decided to quit working was the first time I started it after I had just replaced the connecting rod and main bearings.
Some times it still goes out while driving, it has a bad wire some where. I am going to toss it and install a mechanical gauge in its place.

 

wern't things nice when we realied on carbourators and machines rather than all of this crazy electronincs
