i finally got spark at the plugs today but it didn't start. i have never worked with injectors so how do I check for fuel at the injectors and/or remove them for cleaning. the pump does work as I tested it (well I heard it run when I powered it up) after i put in the new relay and turned the key on i could also hear it run several times. now it doesn't run with the key so i 'm hoping the line is pressured. what is my next step
