Default Injectors not spraying please HELP

Ok guys im dying here I have been working on this car for weeks removed intake and removen then welded EGR and SCV. removed exhaust and welded EGR and the other thing under the EGR that send exhaust through the air intake.

just for test purpose I connected the scv and other little valve

The car turns over just fine. timing is set correctly
Great spark no problems there

Fuel pressure just tested got a strong 43 psi
Tested injector harness have 12.4v when the car is in the on position upon cranking drops to 10.5v.

My problem is that I have no injector spray

have not tested the ecu but I dont really know what to test anyways.

please help

check the plug on the dizzy. They are notorious for going bad. they get loose and the ecu can't get a reading from the CAS and therefore won't spray and fuel.

what he said^ or just plain bad distributor/cas.
depending on what motor youre dealing with.

with the key on, engine off you should be able to remove the distributor or cas, and turn the gear and hear the injectors click.
if ecu is good, which it seems to be, the problem is the cas/distributor.

Did you remove the fuel lines? If so check to make sure they are hooked up right, the feed line coming from the fuel filter feeds into the rail BEFORE the fuel pressure regulator, if not try a good dizzy
