I have a 1999 suzuki grand vitara, I put wrong gas in my gas tank, I NEED.....

how did you put a diesel nozzle in the filler tube for an unleaded gasoline engine? it won't fit because the filler tube is smaller. Also, there is a plate under the neck to prevent any intrusion but the small petrol nozzle, which was designed to prevent drivers from putting leaded(big nozzle too) petrol in the first place. did you not smell the diesel fuel? you were on that cell phone i bet,when this happened!
