New Holland TC45D won't start fuel supply issue

[Happy in NC]

Is there any part of the fuel system that is electric besides the solenoid??

Glow plugs.??

I put that solenoid in and getting a good steady stream of fuel through the banjo bolt but none from the injector or injector pump?? But getting fuel in the return line.
How long should I crank it with the expectation of seeing fuel at either injectors?

The glow plugs have nothing to do with pushing or pulling fuel. Correct?

Pull the solenoid out and try it with it removed,
just be aware that if it starts you will have no way to shut it down.
Except for reinstalling the solenoid, stalling the engine or cutting off the air supply.

Remind me ... the banjo bolt your talking about, where is it in the fuel flow? (After lift pump/before solenoid/injector pump?) A solenoid that doesn't let fuel into injector pump could give you lots of fuel before the Injector pump because you are simply pumping from the tank & back to the tank via a slightly smaller return line, which creates pressure. What you want is to see if fuel is entering the injector pump and coming out of the injector pump. Have you jumped the solenoid while it's on the tractor to make sure it opens & let's fuel flow into the injector pump? My Zero turn had a jumper switch installed when I bought it since the previous owner didn't want to diagnose the loss of power problem to the fuel solenoid. This could still be a bad solenoid or wiring/relay problem.

Thank you

Solenoid is new from NH. The banjo bolt is on top of the injector pump. It will possibly start with solenoid out? Will it idle or run full throttle?
