I have a 1989 chevy camaro rs with a 2.8L. i have tried all i know to get it to start but it just continues to turn over but won't catch. it is getting gas and getting fire. is there anything that i might be overlooking that i can check before having to mess with the timing that might help me. i would hate to scrape this car just because it is starting to **** me off. Please help before i do something i regret!!!
