I can spray carb cleaner into the intake and it will fire. I have over 60Psi. fuel pressure, I performed injector balance test with scanner and all injectors create the same pressure drop. After injector balance test, truck started and ran till fuel from test was burned off. I have cranking RPM and reference signal. I have no codes. Apparently injectors do not fire while engine is turning. The Engine is a 5.7 with Sequential Port Fuel Injection. Where should I go from here?
