a good friend of mine has had fuel injectors replaced not too long at all and the problem is back.. the cyliner is getting spark and no fuel (front cyl). Can anyone help me as to what might be wrong? Fuel filter has been replaced too with a build.  Cams and some valve work..     Thanks.

Filter, pump, line, regulator or anything else in front of the fuel rail should effect both cylinders.  If it's one cylinder and you're questioning something injector related it's worth lifting the tank and closely inspecting the harness to the injector.  It's not unheard of to see problems in the injector harnesses just above the injectors.

Good luck and hope it's something that easy.  Have seen the wires break where they turn "down" to the injector and also one time saw one of the pin terminals in an injector plug not have a good crimp on the wire.
