First off if the check engine light is on please post the codes. If there is a vacuum leak or failed or false signal from a sensor the ECM may be keeping the injectors from spraying fuel.
Have you tested to see if the injectors are firing? That would be important to know.
This is the type of probe tool I use. You just touch the tip of the probe to the side of any fuel injector while someone is cranking over the engine and it blinks when firing. Quick and easy to use.
