7mge turns but won't start

[Raiden93]

Hey I'm new to the site. Novice car guy. Owner of a 91 Mk3 Auto.

My car won't start and I can't seem to figure it out.
For a while now from time to time when I put the key in and turn it nothing will happen other than all of the lights will turn on, radio will turn on, and I will here a single clicking sound. I will play with this for a while and then the car will start up and be fine for a week or two then the problem will occur again. Well the other night I was leaving work and this happened. I got it to start, got down the road a ways and all of a sudden I started to lose power, it puttered, I came to a complete stop at a light and it quit on me. Now the car will either do nothing other than the lights and click or it will turn but not start and then white smoke comes from the TB and exhaust accompanied by the weakest putter and a fuel odor.

I had to have the thing towed home. The tow truck driver said he thought it was the fuel pump. I don't know about this. I am stuck, it is my only car and I need to fix it ASAP. Please help!
