so i just bought a 93 trans am with 136k on it and has a decent amount of mods, h/c ram air, hooker headers, stall, 3.73s ect. i bought it knowing it didnt start, i was told it needed a new optispark so i replaced that, but even now it still just cranks. i pulled a plug and there is no spark. any ideas of what i could check for? much appreciated

ps. first post so please dont be mad if i broke some rules....
