Hello and thank you for your question,

If you are sure you have proper fuel pressure at the service port (32 to 45 PSI) and good spark at the spark plugs then have you checked to see if you have injector pulse at the injectors?

Have you doubled checked the fuel pressure?

Expert:  Ron replied 1 year ago.

There are two pumps in the system as I'm sure you know, the lift pump in the tank and the pressure pump on the frame rail and if the lift pump has failed the pressure pump will push fuel out of the valve but it will not be enough so lets double check the actual pressure. You can also check the injector with a standard 12 volt test light, place the test on on the power wire at any one of the injectors and the ground end on the other wire in the connector and crank the engine over. If you have pulse the light should flash while cranking the engine over. If you have good spark then it has to be either a fuel pressure concern and or a lack of pulse. Check these for me and post back with the results and we can work from there.
