I have gas to cab, fuel pump is on toggle switch and injector is good. But when I hit throttle it does not give gas. People have suggest replace disrupt-er.
Could it be simpler problem like a sensor? Any suggestion before I take that apart and try to replace.

Just started doing work on vehicles so go easy

Good morning.

What is the actual fuel pressure to the throttle body?

Have you checked other items such as catalytic converter for being clogged not allowing the engine to breathe?

What is a "disrupt-er"?
You said when you "hit throttle it does not give gas", can I assume then that the engine will start and idle?
If so, then you could be looking at a faulty throttle position sensor.
A fuel injected engine does not spray gasoline when hitting the throttle like on a carburetor engine.
