So, I have fuel to the rail and it has spark, I know that my cam angle sensor is bad, so I took one off my friends running RB20 S13, we took the fuel rail off and gas is only shooting out of the first injector when u spin the cas and when we try to start it with cas in still only fires first injector. We tried my friends ecu also and still same thing. Also checked injectors with noid light and all showed there getting the signal they are supposed to get. I don't know what to try or check from here. So any help of what to try or check would be apreciated. Thanks.

Bad injectors maybe. Possibly stuck shut or bad coil inside it. Check resistance and see what u get. IDK if theyre low or high impedence injectors but if theyre low they should be between 2 and 4 ohms and if theyre high they should be between 10 and 14 ohms. See what u get and maybe try some different ones and see what u get. Good luck man
