It may be similar to the Tercel, and it is a good starter.

Is it driven daily? Has it been sitting? The more information posted, the better. With this information.....out of fuel, blown fuse, fuel pump, timing belt, fuel filter, dead battery, etc. Does it turn over? Does it try to start but don't? Does it start and die?

Toyota Tercel 1983 1998 Workshop Service repair manual

sounds like a voltage regulator problem

DID you fuel your vehicle just before this, on newer vehicles if you don't tighten your fuel filler cap at least 3 "CLICKS" it will turn on the check engine light. As for resetting the light you need to visit a garage so they can clear the code.

Hi , must be the bulb ( led ) needs replacing if it`s in the middle column than under that "L 2 D N R P" plastic cover.If it`s in the cluster you have to take the cluster (speedo) out and those bulbs usually can be changed from the back of the cluster. Hope that helps.

1999 Tercel rear light bulb replacement. Snap off 2 black caps to pull back carpet. Remove 2 screws on outside of trunk at the edge of trunk lid. The light fixture will loosen up. Sqeeze the tongs on the square white plastic plug on the inside and push plug through hole. You may have to give the light fixture a tug. Turn bulb holder and pull it out. Pull out bulb and put in new one.

sounds like the wiring was repaired and someone tapped into the headlight circuit instead of the parking light circuit

Pull a spark plug first. If its wet with fuel then most likely you have an issue with ignition. If its dry then I would look at your fuel system.
