1992 Chevrolet Corvette Base Hatchback 2-Door 5.7L W/ TARGA TOP

HAVE A 1992 CORVETTE WITH TARGA TOP. IT IS RED . HAS RAN GREAT FOR 3 YEARS. 20 DAYS AGO WE WERE GONE FOR A WEEK. AND IT RAINED A LOT . AND WATER MUST HAVE GOT IN THE GAS TANK. IT RAN 2 SATURDAYS AGO FOR BOUT 15 MINUTES . IT RAN ROUGH. I HAVE PUT 3 GALS OF PREMIUM IN IT AND 2 HEETS. TO DRY IT OUT . OCCASIONALLY I WILL TRY TO START IT . IT ACTS LIKE IT WANTS TO START BUT DOESNT. IT HAS BEEN VERY COLD HERE IN MISSOURI. I AM STUMPED. I WOULD RATHER NOT BRING IT TO THE DEALER. I WANT TO PUT NEW PLUGS. NEW INJECTORS. NEW WIRES . AND I THINK THAT WOULD DO IT. I WILL GET PICTURES UP ASAP. GOOD LUCK. ALL OTHER MECHANICS WERE WORKING WELL. SOME ONE ELSE CAN ENJOY IT FOR A WHILE. **********************NOTE 2 BRAND NEW TIRES ON FRONT . $400 VALUE**************************************************************************************
