Hey I'm new to the forum. I just bought an 88 GT about 2 weeks ago with cylinders 3,4 and 5 not firing and I can't figure it out. It has compression, fuel and spark. I replaced the injectors, plugs, cap, rotor, ignition control module and the coil and still no luck. I pulled the valve covers and spun the crank to check the valves and they all looked good. I even pulled the pushrods and they're straight. I reset my distributor when it was at top dead center and still no luck. The only thing I can think of is one of the PO hacked the speed density system up a bit so I know it won't be happy but I would think it should still fire all 8. I plan to convert to MAF but I would like to at least get the engine to run before I start to dump more money into it. Any ideas as to what it could be? Thanks, Mitch
