92 Camaro with a 350 TBI will not start. Yes the engine was changed to 350 TBI. Any help troubleshooting what I might check. Engine seems to be getting gas but will not "fire". Engine turns over but will not start! Also have had trouble in heavy traffic when you are not giving it gas and stopped in traffic for it to just cut off. It usually will start right back up ....but not this time! Also what type of ignition would it have and could their be some type of "computer problem" with the ignition?
