fuel pump????

I have a 1996 Toyota Tacoma that has been acting like it was going to die on ocassion when I was stopped at a red light. It has never actually died on me yet. Sometimes it's fine and sometimes I'm afraid I will not make it until the light changes.
Anyway, tonight I got in it to leave the house and it was barely running when I put it in drive and started up the road. It was shaking and acting like it wasn't getting enough gas to go down the road. I turned it around and headed back to the house. I finally made it back to my driveway and proceeded to sit there and give it time to warm up (it was a little cold tonight) it finally seemed to have calmed down a little bit as I was sitting there idling in park. As soon as I put it in reverse to leave the driveway it started acting up again and was shaking really bad and I could smell gas. Could this possibly be the fuel pump going out or something worse? Any help would be greatly appreciated. Thanks

Do you have the 2.4, 2.7, or the 3.4 L ?

It is a 2.7 liter.

I am having the exact same problem with my 1996. i have changed cap, rotor, plugs, cleaned maf, replaced tps, cleaned throttle body. have you came up with the solution if so please tell me.
thankyou

You could have a plugged fuel filter. Auto Zone,Advanced,O'Riley's and Pep Boys have loaner tools.

You can have a bad pump or pressure regulator.
