LS160 No Fuel to Injectors...

[Random]

No fuel to injectors but there is fuel and pressure leading up them. No fuel out of Injector pump though. Could all 4 injectors be completely clogged...? Hoping a simple fuse to fix. Yes the Solenoid works but still removed it. Any guidance would be appreciated... Thanks, John

It is possible, i bought a machine that someone managed to mess with before auction, possibly so they could pick it up for next to nothing.
You mention fuel to the injectors, but not out of it. You can dis-assemble injectors or get a shop to do them for you, then you know for sure.
Another test is to just loosen the tube line to the injector a bit of a turn, this way there would be a load on it, so you know there is actual pressure there.

Almost ready to start into this machine...problem is boom is down but I will manage.
After looking at the service manual, the first thing is I will do is remove the delivery valve and check for fuel there while cranking. Afterwards I will remove each injector, inspect and clean.
Here is a pic with the arrows indicating where there is fuel and pressure. The tubes at the top of the individual injectors doesn't appear to be any pressure. At the 1st injector, there is a rubber line head up from the injection pump with pressure.
Again, any advice is appreciated.

In your first post you stated that there was no fuel coming out of the injectors, but there was fuel to them, and that there was no fuel coming out of the injector pump. Those two situations sound mutually exclusive to me.
I would suspect that the fault lies in the injector pump not delivering enough pressure to pop the injectors. The likelihood of all 4 injectors plugging up is unlikely, unless someone dumped a couple bottles of Coke in the fuel, and that would do a job on the whole system.

What was the resolution?
