Have you actually done any logical tests ??

Is the fuel pump running when it should be ? Very simple test. Listen to it ! Or test for 12v power.

If yes, then you could assume it has fuel pressure, but of course it would make sense to actually check.

Are your injectors getting 12v and signal when they should ? Again, simple test. I dont trust noid lights, and a filament type sidelight bulb suggestion is just daft given the short duration of any pulse.

Test with a suitable meter for pulsewidth ( or duty cycle at a push ), but ideally use a scope so you can actually see if it's a regular and consistent pulse at each injector, as well as checking for PW.

Are you getting spark's as expected ?

If you're doing any other tests given you think you've no fuel, your wasting your time.
