Car cranks.Has fuel.Has spark and no start. on 1999 Mazda 626

Car started acting up about a year ago when I started having to replace the spark plugs just to get the car to accelerate properly. has had the timing belt replaced, coil pack, Crank position sensor and cam position sensor..and I can't pull any codes because the car can't even start! any help would be greatly appreciated

IF you have spark(to plugs) AND you have fuel(to cyl.-injectors working) then re-checking timing (For both valve and ignition) might be a place to start.
