Will not start

Just to confirm which light you are talking about, is this the check engine light?

If so, we need to check the codes and see what is there.

Also, if this is just cranking, we are going to need to check for fuel and ignition. However, this buzzing noise that you are hearing does that happen only when you are cranking the engine?

If so, this could just be a drained battery.

If this doesn't sound like what you are dealing with then we need to start with getting a video of this issue so that we can get on the same page.

Please let us know what you find with this, and we can go from there.

Thanks
