Check for proper fuel pressure. The fuel pump or related part may be in need of repair or replacement. You can try spraying a small amount of starting fluid into the intake to see if it runs briefly. If so it is not getting fuel or injector pulse.

Fuel pressure should be 9 to 13 lbs. Change out the fuel filter first.
