I just got finished installing my new injectors in my car and the fuel pump doesn`t come on. I took the fuse out before i started it and it stumbled and died like it was suppose to but now it won`t run.

 

Make sure you put the relay back in the right spot. It is very easy to put the relay back in the wrong spot (I have done it a once before). When you turn the key to the "ON" position you should be able to here the fuel pump making a whirring sound. If you don't hear the fuel pump (it is pretty loud) then I can almost guarantee you put the relay in the wrong spot.
