Hi Ladybee.

Did you connect the battery poles the wrong way, or did someone connect jump-start cables the wrong way?

The former condition is a lot less worse than the latter.

Connecting jump cables the wrong way is quite common but a very unfortunate situation. The smoke probably came from the generator. I'm surprised that the car started in that condition.

Try to take a plug out and connect the cable. Hold the spark plug to ground and see if a spark occurs.

If it doesn't check the coil.

If it does, check your engine management ECU first.

Good luck.


Regards

Geir

With the battery terminal now properly oriented, what electrical systems function? Probably all of them except starting the engine. I'd first check the OVP relay, located behind the false wall in back of the battery. It has a safety fuse built onto the top of the relay, check to see if that has burnt out. After that, it's just a matter of ruling out the different engine circuits, like the ECU, Fuel Pump Relay, etc.

if you reversed the teminals. the starter motor turned the other way.
If the starter turned the wrong way, then you could quite easily have bent your valves as the chain will have gone slack.[xx(][xx(][xx(]

If the starter is spinning in reverse, it won't engage the flywheel.
