Why would I have to remove one of the fuel injectors on a 1999 nissan altima before it will crank?

Question by Eddie G: Why would I have to remove one of the fuel injectors on a 1999 nissan altima before it will crank?
If I leave all the injectors in the car floods out. And if I take one out the car will crank. I put in a new pump and one of the old gas lines from the old pump was melted. Is the return line stopped up? Do I have to blow the return line out or the injectors?

check the fuel pressure and if it goes too high its a clog in the return, if it goes down fast after the pump turns on and turns off then its a leaky injector/ fuel line/ a valve in the pump.

does the car run or anything? what symptoms is it exibiting?
