Something is wrong with the fuel supply. Since you have flow thru the return pipe it means that the problem is either in the pressure regulator or the injector .
To check them you will need to do 2 tests:
1 - to determine the location of the fault detach the fuel line from the injector, put it in a can and try to start the engine - if the fuel squirts with pressure then the regulator is good and you need to test the injector itself;
2 - connect the fuel line back to the injector, put a multimeter across the contacts and check the voltage when you try to start the engine - if it shows less than 6 volts you have an electrical problem (either a faulty wiring or a defective ECM); if it shows over 6 volts you have a clogged injector - the entire fuel system will have to be cleaned.
