I have a 1998 chevy silverado 4X4 5.7L 350. I accelerated a little to much last night and maybe hit 5 thousand rpm's. The then truck started running really bad and sounded like it had the biggest misfire ever. I then pulled over, put it in park, and shut it off. I went to start it again and it would not start. I have checked everything and i dont think it has blown up. There is no anitfreeze in the oil, and the motor still turns over im preety sure. It is not getting spark and i have checked the cap and rotor and both look good. What could it be? Any suggestions?
