What do i need to do to get it started?

Mean stoped running you checked oil it was empty?

Why do you ask?

Well if it ran out of oil then there will be major engine damage

I didn't check the oil level. I just know that it was leaking oil because the oil filter was not put on properly. As I was driving it the oil warning light came on. Sadly, I made the mistake of continuing to drive the van thinking I was close to the house I will check it when I got home. I didn't make it to the house. The engine just stopped running a 1/8 of a mile from the house. I thought I might have run out of gas. But even after adding gas it wouldnt start. I got it towed to my house. After some checking I noticed the oil filter was loose that must have cause the oil mess under the car. I refilled the oil and made sure the filter was tight. But it still would not start.

What can I do to get it started?

most likely will have to replace the otor as you have done major engine damage

Are saying I have to replace the whole engine? If so, can you give an estimated cost of parts n labor?

yes and if you use a used motor, 2200-2500 new is about 5000
