    If the pump was bad it certainly could have cooked the relay.
    Ignition switch is probably the only thing that it could be other than loose or shorted power wires IF these two problems have a common cause.
    1992 ? ...multiple isues stemmingfrom oxidized electrical conections, contacts switches relays etc.
    Be the electrician.

    Perhaps you tripped the inertial cutoff switch fixing flashlights one article suggested it is on the inside of the firewall by your left foot.probably bumped it with your head. Run a search for"92 Fleetwood p90 inertial fuel cutoff switch and you will get pictures of the various style switches and several potentially helpful vids, articles and forum threads.

1992... Fuel pump could be bad
Ignition switch?
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.

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?

    The fuel pump relay has power fuel pump is still not working

  • montehammons Dec 27, 2016

    That's probably all of the fuses. So the relay has power. Try jumping that relay (terminals 30 and 87, I think on those relays) Jumper from the power terminal to the terminal that goes direct to fuel pump-that should tell you if your pump is good or not. If that doesn't make the pump turn on, then only possibly a bad ground for the pump or a bad pump. But if that makes the pump come on, then you have to figure out why the pcm is not signaling that relay to turn on and send power to the pump. Swap another relay in to test if you have a bad fuel pump relay.

    I did a search for 9290 inertial fuel pump cutoff switch. closest I can find by your left foot on the inside of the firewall if you run that search you'll see an image of several fuel cutoff switches so you will know what you're looking for

I have a 3.1 1992 corsica it drives fine but it just dies all of a sudden. it will start back up but then it dies again. the fan didnt work. i checked the fuses all were fine. if its a ground wire which...

Do you notice it dieing in a certain place? Like in a hilly area or on inclines? I recently had a similar problem on my motorhome. I seemed to run fine on the flats or downhill, but when I went to climb a hill, it would die. It ended up being a weak fuel pump, water in the fuel and a clogged fuel filter. So I replaced the fuel pump and fuel filter and put two cans of heat in the fuel tank (75 gallon tank) and it ran great the rest of the way home.

I would check the ignition switch. With a test light, check the small wire going to the solenoid for power when someone turns the key to the starting position. If you aren't getting power to that terminal on the starter, the ignition switch is not sending power to the solenoid.
