Answer
Hello Larry,
You have fuel...is it squirting out the injectors?
If so, check the EGR valve to see if it is stuck open, creating a terrible vacuum leak.
If no fuel is squirting out the injectors, check to see if they are pulsing. If they are, check the fuel pressure at the throttle body. Needs to be in the 13PSI range.

Make sure the rotor is actually turning, although if you have spark, it must be.
