What is engine liter size? Battery has a full charge? Do you have spark at the plugs, engine cranking? Engine cranking, did you use a gage and check proper fuel pressure? Check voltage and ground at fuel injector, engine cranking. The voltage goes hot with key on and is fuse protected. Use a test light. Do you know whether or not there is an rpm signal?
