My car will not start unless I push the car and pop the clutch

--Check and test the clutch switch, starter relay and the ignition switch-double check connections at starter and battery

I have already did all that I may think it could be the flywheel?

Could be the starter not engaging the flexplate or its teeths are worned out-

Just to add to this one what is your car not doing?You said it doesnt start does the starter work?If not do you have a multimeter to do some testing?

When I turn the key to start the car it turns but doesnt start.I just replaced the starter

I need more details what turns the starter is turning without turning the engine over?Or do you have whats called a crank no start?Where the engine is turning over and the engine wont start?
