Civic not starting what is the cause plz help?

ok i have a 94 civic dx...it wont start..im getting spark in all four cyclinder, timing is at tdc, compression is 190 in all four cyclinder, and im getting fuel to the rail...it won't start...but when i spray carb cleaner in the throttle body it start right up ...it seem like im getting fuel to the rail but the fuel isn't getting into the cyclinder,.. is it fuel pressure? should i change the fuel pump? i don't have a fuel pressure tester...i thought it was a clog injector or rail but it wasn't because i replace it and still don't work ....so i need help fast...why is fuel getting to the rail but not going into the cyclinder.....*note* when i spray carb cleaner in the throttle it start right up...is it weak ;fuel pressure???

ok i change the fuel pump but no start...fuel is getting into the rail but not into the cyclinder. i backprobe the injector and use a test light, the light does come on, so im guessing the injector is getting power( if that is how you check it) what are the odd of it being the fuel filter being clog...can it be the computer??? it crank but no start, but with carb cleaner it always start..can it be bad injector or pressure regulator..help asapCivic not starting what is the cause plz help?BELOW drivers side dash to the left, close to the door, above the trunk pop you will find a large realy pack, give it a light tap with the handle of a screwdriver or what not. very common prob on the civic for that relay to get loose internal connections, after knocking on it try to start! if you start up change out that relay pack, on hand at honda dealership, also available for cheap aftermarket too!! had this exact prob with bros civic and this was his problem!!! this relay pack controls fuel pump, starter, and i forget the other thing but anyway the car running on carb cleaner tells me the pump not turning on, which this relay directly controls!!
