Electrical Gremlins
I have '96 Z28 with a mostly stock engine. The car sat for a year while I went over seas (was started far a couple minutes ever couple of weeks) I am having 3 electrical (2 sensors and 1 lighting) problems.
1.) (Newest)The problem is that when I go to start the engine sometimes the "Low Oil" light will come on however, the oil pressure appears to be normal and the oil level is good on dipstick. If I shut the car off and start it up again it will go away. I'm thinking the oil sending unit is going bad and wanted to know if there were any other ideas that I might want to check.
2.) (about 17 monthes old) I had this problem before I left.The problem is the "Low Coolant" symbol light will come on like whenever the temp reaches about 210. When the engine cooled I check the coolant level and it was still full so I am not losing any coolant.
3.) Had this problem about as long as above. The last one is that some times when I go over a bump the lights will sometimes come on and sometimes turn off right away and ather time will stay on for a minute or two. All the doors are fine and the trunk lid seems fine. I'm thinking the latch needs to be replaced. I went ahead and removed the dome light and unpluged the lights in the mirror.
Plan to look into these poblems this weekend and wanted to see if anyone had any other ideas that might cause these problems.
Thanks

Re: Electrical Gremlins
Coolant level sensors are a common failure on 4th Gens; easy to replace. The flickering interior lights are usually associated with a hatch that's not fully closed. If your latch is closed, take a look at the switch and see if it is broken/mispositioned. The oil level sensor is different from the oil pressure tranducer. The level sensor is mounted in the side of your oil pan on the driver's side. The wires to the csensor run close to the exhaust so I'd check for a burned wire.

Re: Electrical Gremlins
Thanks OBE1 95Z28.
I will have to remember to check the wires. I meant to say the oil level senor. I will check to see if the trunk switch is broken or mispositioned because the trunk seems to be close because I can push or lift on the trunk and the light will stay off (could still be the latch though). Thanks again.
