maybe test the fuel pressure.

Todd,

You may have an immediate hazard on your hands.  Be careful.

You REALLY need to figure out if that gasoline odor is from the tail
pipe or not.  This is the difference between an engine issue which
others have been discussing, and a broken fuel line which is a
completely different process of diagnosis and is very hazardous.  If not
the tail pipe, then read on.

This bothers me:  "The gas smell gets stronger when I engage the fuel
pump without turning the motor."  Very bad!  That is what you would
expect from a break in the fuel line somewhere under the rear of the
car.

Where is the fuel pump located?  Run the pump for a few seconds, then
start checking everything between the gas tank and the engine for a
visible leak.  Start at wherever you think is the source of the odor.
Youy're going to have to get under the vehicle of course.  In particular
check around the fuel line connections on the gas tank.

I must remind you of stupid common sense stuff like only work on this
outdoors and don't do anything that might make a spark near gasoline
odors.  (Spark tests inside the engine compartment are okay if it does
not reek of gasoloine.)

DO NOT go under the car with the fuel pump turned on.  You might want an
assistant standing by with a fire extinguisher.  Non smoker of course.  
;-)

Please don't make us read the end of this thread on the five o'clock
news.  Good luck.
