Most important thing you need to do is to establish the actual oil pressure. put a mechanical gauge on the engine and read real oil pressure. If pressure is low (min is 15psi, I prefer to see at least 20 at idle) there is an internal problem...bearings etc. If pressure is good, sending unit has failed...replace it. I would not drive it 'till the oil pressure is verified as being safe. You might get lucky and someone just forgot to plug in the sending unit, but it must be checked!!!

Check for fuses and fusible links that may be tripped or blown.
Next, check for grounding issues someplace easy to reach like the heated seat connectors.
Most dummy lights work by choosing the warning light path over the circuit path when the circuit path is higher resistance. Which may explain your dash warning lights.
So, what I am trying to say is...you are looking for a open ground in a big big place....like under the hood at one of the major fuse/relay/fusible link points.
Check it out. Good luck and be careful.

SOURCE: Service engine soon light
The service engine soon could be an indicator that you need to have minor maintenance done in the near future. I had a Grand Am that the service engine light would turn on when I was getting close to needing an oil change. You might check your owners manual for an exact reason as to why it turns on.
