the fuel pump was just replaced and so was the filter, i was thinking mabe the injectors might be bad. but the problem is that i dont want to buy new injectors if there is something else i should check first

Does it crank for a minute when its warm? If so you need a main fuel relay...about $50 at Autozone.

the car runs fine sometimes but starts to bog up and down then shuts off and it wont start, sounds like it wants to but it wont.
