Hi,

Does anything electrical work? For example, if you turn the headlamps on, do they work? Do the interior lights work? How was the battery tested?

If the headlamps work, try this test.

Let me know what you find. Also, if you have a spark plug that has come out of the engine, you really shouldn't run the engine.

Let me know.
