Hello and thank you for your question, My name is ***** ***** I will assist you today.
When you say the pump is working does that mean you have good fuel pressure at the test port (32 to 45 PSI) ?
If the fuel pressure checks okay have you checked to see if you have injector pulse?
Expert:  Ronnie replied 2 years ago.
To check for injector pulse, take a standard 12 volt test light and place the test end on the red power wire at the injector connector and place the ground end on the other wire and then crank the engine over, if you have injector pulse the light should flash while cranking. Check this and post back with the results and we can work from there.
