I can't recall as its been a while since I've worked on the older Civics, but there may be 2 bulbs in the cluster. They are not that hard to pop out and have a look.

The first thing to do is have the battery checked and the battery cables, repair any problems found like cable corrosion.

Send us a description about this light? Check engine ir some graphic there?

if car not starting.it could be fuel pump, filter or starter motor failed.

Check the injectors..

Try jump starting the car

have your charging system checked, you may have a bad Altenator

that small orange motor on the dash is the engine managment light this means one of the lamba sensors on the exhaust system is faulty

yes it means its time to change the oil

have you check the ground wire from your negative wire to battery post? check to see the battery is strong. if it doesn't turn over the engine or crank the engine mean no good ground to the cables. if the car ran fine I dont understand why the car wont crank or turn the motor over it just quit. if the battery check out strong 12 V, starter serenoid may be faulty on your starter or it may be hot and will not turn starter over.
