1998 Other Volkswagen Models Two Wheel Drive Manual

HI there, I have a 98 VW transporter duel fuel, my problem started yesterday after filling up gas, started the car about to leave the servo and as I started the car I heard a back fire / pop for around what I thought is the air filter. The car now has no acceleration.
i have change spark plugs and leads and it is still the same. Its like it dies under acceleration.
the car now dosent start on petrol only lpg, but it use to run fine on both lpg/petrol before the backfire.
thought it may of been fuel pump, but the fuel pump primes, and it dosent explain loss of power on lpg.
i have checked all fuses, all 5 spark plugs are fine, all 5 leads producing spark, dissy is ok.

what else can it be?
sorry for long post but needed to explain all

hope you can help
