Hello. My name is ***** ***** I will be assisting you today. It sounds like the vehicle has started skipping cylinders, which means that it is misfiring, probably due to faulty spark plugs, or coils? This could also be do to the cam or crank sensor(s) not functioning properly. Just a moment, please. In the meantime, when was your last tune-up?
The fuel pump could definitely be the cause. If that is the case, then the pressure will need to be tested. Here is some general information for you vehicle on misfiring. Also, the partial engine sign is just saying that the vehicle is not firing as it should.(which could be due to low fuel pressure also).
Ultimately, you will have to have to vehicle scanned first. The code that is given will point the techs in the proper direction to begin diagnosis. Although, I am assuming the issue to be misfiring due to low fuel, a faulty cam or crank sensor, or plugs/coils. Once the dealer scans the vehicle, they will know the problematic area.
The fuel smell is due to improper combustion(misfire). The fuel is not being burned. You will need an OBD 2 scan tool in order to check for codes. You can also take the car to Autozone(if the vehicle is driveable) and they will scan the codes for free.
You can purchase and inexpensive scan tool for around $40.
I don't know how bad the issue is, or what the issue is, so I can't honestly say that the vehicle is safe to drive.
The scan tool connection is located under the dash on the drivers side.
This is just general location information to help you find it.
