Answer
There are 2 possibilitys,
1. You may have a bad coil pack that will not send spark to the plugs.
2. Then again you have a fuel pump that isnt working at all

I would have the vehicle serviced, and it will cost you more money, but vehicle repairs are not cheap. I would suggest getting it fixed, and then trade it in. Sounds to me this vehicle is costing you more money than its worth... Ty..
