    Can anyone tell me how to test the fuel door switch? Trying to diagnose. Fuse and relay are good.
    Any help would be greatly appreciated. Thanks

    what's it doing wrong? In my 348, the ignition switch has to be on. (or something is terribly wrong with mine)

    My Fuel door solenoid got crudded up over the decades.
    A quick shot of WD-40 and some forced actuations cleaned out the junk and it now works fine again.

    WD-40 & execising a bunch of times in a row solved my sticking issue.

    Check the wiring plug at the rear of the solenoid too. Mine was intermittent and I found the connector to be corroded. I changed it for a better type and its been perfect since.

    It's also a momentary switch so you could pull off switch and jump across the connector wires and see if you here the solenoid click (or door open)

    That’s what I’m wanting to do but there are like 4 wires going to the switch. If I knew exactly which wires to jump that would be ideal. Any thoughts?

    2 wires are for the illumination. Disconnect the switch, use an Ohm meter on the switch (will need a helper), probe the switch contacts while helper actuates switch. You will go from open to closed once you find the contacts. Then you can transfer that to the connector side.

    Or just push it in and let it pop out 10 times and it will likely work?
