Hello,

It sounds like you might have a fuel leak under the hood.
First you will need to do a visual inspection to detect the leak. You want to look especially around the fuel rails.
This leak could be a leaking seal on the injector or one of the fuel line that goes to the injector could be loose and leaking.

You might want to turn on the key (not start) and see if you are able locate the fuel leak.
Please keep in mind that leaking is dangerous as it can drip on the exhaust manifold and combust.

I have attached fuel injector diagrams for your reference.

Please let me know of any questions.
Thank you.
