ok guys... been puzzled past couple days im getting fuel up to the rail but not one of the injectors are firing, and all the connectors have been checked and their all receiving a signal to firing with switch turn to start.... could all six injectors be bad.....??????????????????

It would be a big help to know what car this is. A common problem on 88 and later M20 powered cars is corrosion in the C191 connector (just below the intake). That can disable all or half of the injectors.
