6 cyl injectors in a 4 cyl toyota ?

I have bought a Toyota 4x4 that has the 22r motor and is fuel injected. The truck is getting gas through the fuel rail and over the top of the injectors but is not starting. The truck turns over when I turn the key. It also fires on ether and when I atomized gas into the planum (or w.e. you call the thing that says EFI that sits over the fuel rail). The injectors were pretty clogged up and the O-rings were shot so that's most likely the problem. I know where I can get injectors for a 6 cyl Toyota EFI but I don't know if they will work with my 4 cyl. So that's my question. Also any other suggestions are welcome. Thanks!
