2002 Volkswagen Jetta fuel system problems

My 2002 volkswagen jetta gls turbo, 26,000 miles caught on fire in washington state while on the highway. I smelled gas while driving and pulled over opned hood and a fe seconds later a fire started. While on the phone with 911 there was a minor explosion and I received minor burns to the face and hands. Vehicle was towed 20 miles to karmart VW in burlington, wa. The next VW of america called and said they were investigating it. Three weeks later they called and denied the claim for repair or replacement.

My 2002 VW jetta, VIN# [xxx] has approximately 22,334 miles on it and has been at pacific VW since march 18, 2004. The concern with the vehicle, which the dealer/factory reps have been unable to remedy is with a complete loss of acceleration. When depressing the accelerator pedal, the vehicle will slightly accelerate to about 15-20 MPH and then the vehicle will not propel forward at any faster rate, even with the pedal all the way to the floor.
