It will start only by holding down on throttle, but will shut off if you take foot off.

Good morning,

Is the check engine light on? If it is, do you know the code?

Some possibilities:

1. Fuel pressure.

2. Clogged catalytic converter.

3. Low engine compression.

4. Engine timing.

All these need to be checked to determine the failure.
