Having problems with your 1992 Mercury Topaz ?

My 92 topaz doesn't start, so i replaced the battery, fuel filter and fuel pump and it still wont start. it has enough gas and the fuel shut off switch is pushed in good. the day it broke down i just drove it on lunch like 3 hours before. the engine turns over but that's all. it sounds like it wants to start but it just can't. it's good on oil also.
