Question about Cars & Trucks
Fuel pump is not working
1992... Fuel pump could be bad
Light switch or the dash light dimmer.
At this age all rubber, vacuum lines etc.
And electrical conections including the fuse and relay panel contacts are suspect.
Reinserting fuses and relays may reestablish continuity, however a deox spray cleaner and dielectric grease will prevent reoccurance.
As for ignition switch unless a contact inside is just terribly burnt , the contacts block can loosen up and prevent power from getting to various systems. Jiggling the connector will demonstrate this being an issue
Inertial fuel cut off switch could be an issue.they are there to cut fuel flow in the event of accident but can be trggered by jarring from any means and often forgotten about.

Testimonial: "Where are the fuel cutoff switchs located"
You need an electrician. He will probably need a wiring diagram to figure out what circuit has the malfunction. Have you checked to make sure the fuel pump fuse has not blown?
By jumping the solenoid, do you mean you bypassed it? I don't even know what solenoid you are referring to.
The pump circuit, if like other GM vehicles of those years, probably has a fuel pump relay (under the hood) and a fuel pump fuse- probably a 15 amp blue fuse, could be under the hood or under the dash. If you check all fuses, then find the pump relay, now you can check there for power available to the relay. The pcm is what signals this relay on. Does your pcm have power? Does your check engine light come on when you turn the key to ON?
